Dolphinite no longer here Posted August 13, 2010 Share Posted August 13, 2010 Anyone know what the torque should be on the dual wheel lug nuts? I just got four new Yokohama tires back there and the dealer didn't know for sure what the torque should be. He set them at 100#.

Derek up North Posted August 13, 2010 Share Posted August 13, 2010 It's quite a bit higher than that. More like 150-170 ft-lbs. Haven't got the reference right now. And it seems there's more than one number floating around, too. Quote Link to comment Share on other sites More sharing options...

And it seems there's more than one number floating around, too. My manual calls for 170. My torque wrench though will not go that high.

Derek up North Posted August 18, 2010 Share Posted August 18, 2010 My old torque wrench only went to 150 ft-lbs. But I got lucky at a garage sale this weekend. A Snap-On torque wrench that reads to 175 ft-lbs for $5.00!! Not a 'clicker', but I'm not about to complain! Quote Link to comment Share on other sites More sharing options...
powdrhound Posted August 27, 2010 Share Posted August 27, 2010 If I weigh 170 lbs and stand 12" out on a breaker bar, I have torqued it 170 ft-lbs. Used this last week when I had to pull off the wheels to remove a 3" rock that had wedged itself between them. I must have stopped directly on the rock, as it happened at a stop on hiway 88 west of Carson Pass. Big clunk after turning around on the USFS road. Could not hammer it out, so had to pull the wheel. The lug wrench worked great. Put it on the nuts and stood on it. Popped off nicely. For the final tightening, with the lug wrench bar being about 12" long, I stepped up on the bar and let it settle with my weight. Checked out fine when I got home. This was not the first rock of the trip, but the only one I could not pull out. But I successfully skied this Patch. Quote Link to comment Share on other sites More sharing options...
Derek up North Posted August 27, 2010 Share Posted August 27, 2010 I'm wondering if letting the air out of one of the tires would have let you remove the rock without removing the wheel. Of course this solution would only be useful if you had an air supply to re-inflate it! For the record, it's possible that late '80's Owners Manuals gave a tightening torque of around 140 ft-lbs. Anyone got one to confirm? Quote Link to comment Share on other sites More sharing options...
JUSTABANGER Posted August 26, 2014 Share Posted August 26, 2014 So all wheels are torqued at 170 I was thinking I read 110 on the front. Quote Link to comment Share on other sites More sharing options...
jmowrey Posted August 26, 2014 Share Posted August 26, 2014 My 85 Dolphin has a little metal plate on the coach just above the rear tires. It says 80# torque. The guys at Discount Tire who just today put tires on for me said the same thing, before they saw the plate. We didn't discuss the front tires. I assume the knew what they were doing.

Derek up North Posted August 26, 2014 Share Posted August 26, 2014 The plate showing 80ft-lb would have been installed when it shipped with 'foolies' installed. Do you still have the 5 lug axle? Quote Link to comment Share on other sites More sharing options...

Derek up North Posted August 27, 2014 Share Posted August 27, 2014 These are the torque values I've seen documented:- 1988 FSM lists 141ft-lb 1993 FSM lists 170ft-lb 1992 Owners Manual lists 170ft-lb for DRW I see no indication of a lower torque value for the front wheels. Anyone have a 1986 Owners Manual to see what (if anything) is listed for the 6 hand hole rims? They have different lugs and nuts to later axles. EDIT: And of course the only other FSM I know of online (1985) doesn't have a torque value for duallies. Does anyone know if the 'Axle Recall Kit' from Toyota came with any documentation with a torque value? I'll (dangerously) assume it would be 170ft-lb since the recall kits were issued in 1991.

JUSTABANGER Posted August 27, 2014 Share Posted August 27, 2014 I just came back from making an appointment to have my front wheel bearing packed. When I told him the lug nuts were to be torqued at 170# he gave me look like I didn't know what I was talking about. Quote Link to comment Share on other sites More sharing options...
Vanman Posted August 28, 2014 Share Posted August 28, 2014 Yeah,,, Subaru tell me to put 32# in front and 30# is rear tires. Sooo underinflated it doesn't even steer rite!!! 35# in all four works great feels like a great steering car that goes exactly where you point it. Was talking to a mechanic at a dealership that had one like mine and when I asked him what he ran in his he said 35 # in all four.... Just because someone says it doesn't make it right. I run mine less than that, done with a torque wrench. I think that you may very well get away with that 170#, but it's too much for me. YMMV john Quote Link to comment Share on other sites More sharing options...
Derek up North Posted August 28, 2014 Share Posted August 28, 2014 ... it's too much for me. Can't say I quite understand. Too much what? Clamping force? Trouble? I'd say, rather, that you're 'getting away' with using less torque, rather than 'getting away' with the factory torque. So how many ft-lbs do you tighten yours to? And if you're not following the factory spec, is it worth the trouble of using a torque wrench? Quote Link to comment Share on other sites More sharing options...

And if you're not following the factory spec, is it worth the trouble of using a torque wrench? He's talking about drivability so I think he got mixed up with tire pressure. Torque doesn't affect drivability unless it's too loose and your wheel falls off. No worries John.

Vanman Posted August 28, 2014 Share Posted August 28, 2014 Sorry for such a poorly worded post, late nite, long day and not thinking well. I have my wrench set for 150#. john Quote Link to comment Share on other sites More sharing options...
jmowrey Posted August 28, 2014 Share Posted August 28, 2014 Okay, I'm no mechanic. Not even very mechanically inclined. The lug nuts on my dualies are so tight (at 85lbs as set by my mechanic) I need a cheeter bar on my lug wretch to loosen them. Seems unlikely to me that the nuts are going to vibrate loose and my wheels are going to fall off. So what are the issues involved with torque? What will happen if they are either too loose or too tight? So many different opinions and not much clarity about the risks involved. Whose advise is the safer? Call me confused and concerned in Santa Fe. Quote Link to comment Share on other sites More sharing options...
JUSTABANGER Posted August 28, 2014 Share Posted August 28, 2014 I've never owned anything with duel wheels before. So when I heard 170# I thought someone had made a typo but I guess not. Now I'm going to buy a torque wrench just for my RV. Quote Link to comment Share on other sites More sharing options...
Derek up North Posted August 29, 2014 Share Posted August 29, 2014 So many different opinions ... ... and one fact. Toyota takes time to publish the torque values. Quote Link to comment Share on other sites More sharing options...
Nam Posted August 29, 2014 Share Posted August 29, 2014 Great, I did under torque mine at 120# last night...good thing haven't put the motorhome on the road yet. Thanks for the valuable info. I will set it at 170# if my torque wrench can go that high ortherwise...breaker bar after that. Quote Link to comment Share on other sites More sharing options...
jmowrey Posted August 30, 2014 Share Posted August 30, 2014 Again, I ask, does anyone know what the consequences of too little or too much torque might be? My Dolphin has been on the road with 85# torque since I bought it last year. I'm still alive and there are no problems that I am aware of resulting from this. Both the tire place and my mechanic seem to think 85# is correct (independent of each other and independent of the little metal plaque on the wheel well about the tires, which apparently was intended for the original 5 lug axle, not the updated 6 lug axle which I have.) They must be getting this spec somewhere. What is going to happen if the dualies aren't torqued correctly? I'm hesitant to more than double the torque without knowing what might happen of they are over-torqued. But I'm concerned about what might happen if they are too loose. Anyone? I guess I'm inclined to leave it as is, going with the theory that if it ain't broke, don't fix it. Quote Link to comment Share on other sites More sharing options...
whyverne14 Posted August 30, 2014 Share Posted August 30, 2014 Sometimes you have to ask the right question. "How many people here had their wheels fall off"? I'm guessing none, so I'm not going to think about it anymore. Quote Link to comment Share on other sites More sharing options...
Derek up North Posted August 30, 2014 Share Posted August 30, 2014 Sometimes you have to ask the right question. Toyota called for 141ft-lb (1988 FSM) and increased it to 170ft-lb (1993 FSM). So my question would be "Why, if 85ft-lbs is enough?". We're all free to try to outsmart Toyota engineers. Quote Link to comment Share on other sites More sharing options...

Gee lots of them still out there and didn't break. Why change it. I don't think I would personally worry if you were at least in the low hundreds but 85 is crazy low. I see some mention of low wheel torque in the front with independent front suspension causing bearing failure and low torque causing excessive bolt heat which makes them fail too. Either way your flying down the highway without a wheel. Linda S Quote Link to comment Share on other sites More sharing options...
ToyoGuy Posted August 30, 2014 Share Posted August 30, 2014 Hmm, my Harbor Freight torque wrench tops out at 159 Lbs and I'm betting I'm loosing some force using 2 extensions to get the angle square and safe/correct. Guess I better put an 8" extension on the shopping list. Does anyone use a little "anti-seize" compound at those upper torque ranges mentioned? I can just see myself packing a 4' cheater bar back there with everything else... TG Quote Link to comment Share on other sites More sharing options...
Gary_M Posted August 30, 2014 Share Posted August 30, 2014 For a cheater bar I use the table pipe from the coach. That'll break anything. Quote Link to comment Share on other sites More sharing options...

zero Posted August 30, 2014 Share Posted August 30, 2014 The lug nuts on my dualies are so tight (at 85lbs as set by my mechanic) I need a cheeter bar on my lug wretch to loosen them. Seems unlikely to me that the nuts are going to vibrate loose and my wheels are going to fall off. So what are the issues involved with torque? What will happen if they are either too loose or too tight? So many different opinions and not much clarity about the risks involved. Whose advise is the safer? 170-180 pound feet dry, and 135 pound feet lubed is the rating for the studs and nuts. Ford and Chevy use the same size lug-nuts and studs on their 1 ton pickups and also call for 170 lbs. tightening torque. M14 X 1.5. Considering the Toyota only has 6 lugs instead of 8 like the Chevys and Fords - I'll assume the Toyota needs that extra wheel-nut torque even more, not less. Having nuts too loose can wind up with them working loose. Having too tight means that the stud has been stretched beyond it's yield point and it basically weakened and ruined. A metal bolt or stud is basically just a spring. When tightened it is stretched and has tension. If stretched too much (with excessive nut-torque) - it is ruined. Just like a coil spring that you pull too far open. Those wheel studs must be very high tensile alloy to sustain that kind of torque. A 14 mm grade 9 lug-stud or bolt is made to handle tightening torque like this. If dry with NO lube - up to 180 foot pounds of torque. If lubed with oil, grease, Never-Seez, etc. - tightening torque is 135 foot pounds. And note that "Never Seez" can be many types of lubes. Many variations.

DanAatTheCape Posted September 1, 2014 Share Posted September 1, 2014 I have a toyota operators manual that lists 100lbs for dually rear ends I use a "cheater bar" (piece of pipe about 18" long) on a large 1/2 ratchet to tighten as hard as I can.

Nam Posted September 8, 2014 Share Posted September 8, 2014 From various sources...and practically, I set my torque wrench at max (150lbs), clicks and I use the breaker bar (or cheater bar) to tight a little more; this makes me comfortable enough for now. Anything below 100ft-lb is way too low in my opinion as a regular small car often calls for 80ft-lb Quote Link to comment Share on other sites More sharing options...
