Need A 6-Lug Full-Floating Rear Axle Assembly

[Lisamorris]

I have been given a 1983 Toyota Huntsman. I brought it to the shop yesterday for new tires - and... they couldn't do it. They had never seen the funny dually rims before and said their machines wouldn't be able to handle them. So... I started researching those funny rims with 5 lug nuts, and - well, learned a lot. So here we sit.

I have spent the day scouring online for a used 6-lug full-floating rear axle assembly. Has anyone seen any recent listings for the axle?

Shipping is often the deal-killer. Plenty of FF rears around the country but finding one close may be difficult. Also -some places charge extra if they have to remove it from the truck or RV. Here are a few listings. Make sure to confirm these rears use 6 lug X 7.25" bolt circle wheels. You might want to consider getting the front 6 lug hubs to match the rear so one spare will fit all (along with 7 wheels). Finding an worn out or rusted out 1 ton U-haul type box truck complete is often a good way to go. I've bought several in the $500 range.

Thank you, so much! I really appreciate it.

Well - I have mechanic friends close to a couple of these places who would help with removals. But as you said, shipping will be the issue. I'll start contacting them to see what it is going to take. Thank you so much for these leads!

Using this site you might be able to find one close to where you live.

Put in 1990 for the year. Toyota truck. axle with housing, then your zip. You'll get listings nationwide but you'll need to start calling cause many of these listings are not updated frequently.

Be aware the you will need new shock mounts welded, brake cable modifications and new wheels if they don't come with the axle. Total cost will probably be more than your 83 is worth unless your mechanic friends work for free.

If you really need tires on it to drive it now -just go to a shop that will mount the tires by hand. It's no big deal but many are just spoiled with their tire machines doing all the work. Dealers who sell ag or industrial tires do many by hand and doing it on a little Toyota is easy with the right tools. I realize though that will not solve your long-term issue of a rear axle too light for the job. As to the mods needed to put in a dually? I've done it on a 78 and an 85. On both - the original brake cables fit the FF 1 ton axle with no mods. On the 78 there were the issues of the stabilizer bar mounting and shock mounting and spring perch locations.. No welding on the truck needed for the shocks though. Just different bottom brackets. A 1 ton FF rear doesn't care where the shocks are since the shock mounts are on the truck frame (on top) and u-bolt brackets (on the bottom). On a 1983 - the original brake cables should fit fine and so will the spring perches. In reference to shocks - I know on the 1985 I did - I just reused the bottom brackets and mounted the shocks the same way as with the original rear axle. Not sure what a 1983 looks like. I do know that sometime during the late 70s or early 80s - the diameter of the rear axle tube changed. The old tubes are only 2 1/2" diameter and the newer including all the 1 ton FFs are 3 1/8 diameter. Subsequently - if your 83 has the smaller 2 1/2" axle-tube diameter - the u-bolts and bottom brackets that hold the shocks will not fit the new FF rear. So that would mean new u-bolts, new bottom brackets, etc. A lot of work and a lot of expense if you're paying someone else to do the work. If you are seriously considering a rear axle swap - I suggest you have someone measure what you have now. #1 measure the distance of the centers of your leaf springs, and #2 measure the OD of the axle-tubes where the u-bolt attach to the leaf springs. A 1 ton FF rear axle will be setup for leaf springs that are 39 1/4" apart (measured on center), and ax;e tubes that are 3 1/8"OD. If your 1983 has those same specs -swapping in a FF rear axle will be much easier. Some older trucks have springs that are closer at 37" and axle tubes smaller at 2 1/2".

Thank you all so much for this help! I appreciate it very much. Well - it is a big question how much money to put into a rig like this. I have been blessed with very kind mechanic friends who have done amazing things without asking anything in return.

I don't know how long they will continue to extend that grace though - and I don't want to abuse the kindness.

I needed a motorhome to help with work I have been doing - advocating for abused and neglected kids on reservations. These generous men have been helping to keep the work going.

I will show them what you have written and leave the decision with them as to whether this rig should be fixed up or not. If this isn't the right rig for me - we will figure something else out.

I have a FF rear axle for sale if you are still looking for one. I'm on Washington's Olympic Peninsula. Let me know if you're interested!

I'm just jumping to this after doing a google search looking for a used full floating 6 lug rear axle for our 1984 New Horizon Toyota. I haven't had any luck finding anything at all. We live in the Seattle area. I see that Jeff listed one on the Olympic Peninsula - any chance it's still available? Does anyone know where else I can search. Right now our rig isn't moving due to the rear axle issues...

[linda s]

Call these places. All found on the car-part place I posted earlier. Don't forget you need the wheels too. If they have the axle they also might have wheels. Try to make a package deal with them

I see that Jeff listed one on the Olympic Peninsula - any chance it's still available?

I'd suggest you send him a PM in case he doesn't see your post.

Great suggestion!

Another option is to replace with a beefy single axle like a tundra, and not have to deal with duallys and save on tires.

Yes - but that means bigger tires and higher off the ground. Also means little chance of ever having one spare tire that will fit the front or the back.

[linda s]

Why bigger tires. There are plenty of wheels available in 14 inches with the same lug pattern as the T100 or Tundra. These older motorhomes have a 5 lug in front anyway and the conversion to six with the flipped dually is not something most want to do nor are the parts easy to find. This is the advantage of having duallies in the back. Get a flat there and you can still get to a gas station. My 86 only has a spare for the front.

A 20-21 foot Toyota is back-heavy. Kind of tough to find single tires in 25.5" diameter that are going to provide anywhere near the OEM load capacity of the dually 185R-14C tires. I would not drive one with rear tires that had a total load capacity of less then 4000 lbs. The OEM setup is over 6000 lbs.

What tire do you know of in the 25-26" diameter range - regardless of rim size -that is rated 2000 lbs each or more? Might find a few aircraft tires that run 120 PSI that come close. Maybe some real wide ones I'm not privy too? The old HD standard for 8 ply wide 14" used to be H70s. They are 28" diameter with a 2000 lb. rating.

Winnebago Phasars and LeSharos get by with single 14" in back and near the same GVW as a Toyota. But the Winnebagos have much more even weight distribution from front to back - unlike the Toyotas with most of the weight on the rear. Those Winnebagos use single 215/785-14" truck tires that are 27.5" tall.

With duallies - yes you can drive with one flat. And if you do so unaware of that flat at sustained high speeds - you can have that flat catch fire.

For me? For a rig I travel with into remote areas - I want a spare for the front and/or the back. Pretty easy to swap in 6 lug front hubs in a mid-80s to newer Toyota. Can also be done in an older truck with front coil springs like my 78 Chinook has. Not so easy as the newer trucks though.

I don't care who puts what into what. To each his (or her) own. Just pointing out what I see as advantages and disadvantages.

Plenty of brand new cars now come with no spare tire at all. So it seems many are fine with relying on roadside service. Not for me.

I don't quite understand your need for tires the same diameter as the 185's. If you put the same tires front and back what's it going to matter. Yes here are way bigger load range and still stay 14 inch wheels. The 205R14 specifically.

I never said anybody needs anything. I stated that single tires would require going bigger . Going bigger means making the RV higher and increasing wind-resistance and lowering MPGs. It also means throwing the final-drive ratio out-of wack - along with the speedometer. Maybe to some that doesn't matter. To me it does. Part of what makes the Toyota RVs unique is they are small, low, and get pretty good gas mileage. Going with larger tires will diminish that.

Regardless - back to my original point that you seem to disagree with. Single tires mean bigger in some way (wider or increased diameter).

http://www.ityre.com/en/tyres/catalog/sonny/size/122989/

They are 1.5 to 2" bigger diameter and throw the speedo off by 3 MPH. But - probably the best to be found near the correct diameter.

[Derek up North]

[linda s]

And I don't think 3/4's of an inch is ever going to make any difference in anything. I get more rise in just a 10lb adjustment in my air bags. Tires are available that are capable of holding the weight and it is an option to go to single wheels.

.8 inches bigger in diameter. A whole 20 less revolutions per mile. 2% discrepancy in MPH which would be undetectable to most people. The later model Winnebago's came with a 195 tire so in that case your going back to factory

Hey - isn't that Strother Martin on the left? One of my long-time favorite character actors - along with Jack Elam. Looking at Strother later in life it's hard to believe he was a pro swimmer and diver at one time.

Yes - .8" for some brands and 1.5" for some others. The official sizes as of 1965 for 8 ply radial truck tires were: 185R-14" = 25.5", 195R-14" = 26.2", 205R-14" = 27", 215R-14" = 27.5", and 225R-14" = 28". Still has little to do with the comments I made.

My comments were in direct response to . . . "Another option is to replace with a beefy single axle like a tundra, and not have to deal with duallys and save on tires. My focus was the loss of load capacity inherent with duallies unless you go bigger. Using two single 195R-14 tires does not come close. Never said it would not be enough to satisfy some users. Just does not come close to replacing what was had with the duallies. Not unless you stick in something like 16" tires from a 3/4 ton pickup like 235/85-16".

Also - back to the same comment with the "beefy" Tundra axle. The Tundra axle-assembly when it comes to ability to bear weight is just a hair stronger then the rear used in single-wheel Toyota pickups from the 70s and 80s. Tundra axles are exactly the same diameter as used in a 70s Toyota pickup. In fact the axles in a Ford Ranger are a little larger. Not exactly a HD substitute for a FF dually Toyota rear. The Tundra does use sealed-ball-bearings that are 2/10ths of an inch larger then in a 70s Toyota pickup. About the same size as used in many 1/2 ton F150 Ford pickups.
