Toyota Motorhome Axle Facts!

Axle Facts, Questions & Answers is a place to post your questions regarding the old and new axles our Toyota Motorhomes have. 1985 and earlier Toys came with a non floating type axle subject to breaking. 1986 and later were equipped with a full floating axle.

I decided this thread should be left open for questions and answers.

I had serious concerns about the axle on my '84 Odyssey and assumed that it had been part of the recall. I finally checked out the NHTSA website and found out that the recall applied only to some 180 models sold in '85 and '86. And not to the ones manufactured by General RV (which mine is).

This was a very pleasant surprise, but I'm no axle expert and now I'm curious what makes mine different.

Should I still have any concerns?

Thanks

I am looking at an early version (1979) of the Sunrader that is 17 feet long. Would the 5-lug axle be considered safe or should one replace it with the 6-lug dually?

Thanks. John

If you could, send another post and attach a picture or two of your axle, showing the lug nuts , differential, and so forth, maybe we all could compare it to what we have to try to identify the beefed up 5-lug axle.
I found a place that will actually make a brand new axle of almost any type, including the 6-lug full floating axle.
Here is the link to it : http://www.diamondaxle.com/index.htm
I don't know the prices or anything.

I'll see if anyone is still reading this thread! I just got a 1977 Chinook (pop-top) that is 17' long and it has single rear wheels and a 5 lug axle. The axle FAQ mostly talks about 18' and longer vehicles and the recall website doesn't seem to want to display any recalls for 1977 other than for Toyota Corolla. Any idea how I figure out if my rear axle is safe. The vehicle has 140K on it and seems to have been a lot of places, should I just not worry about it at this point?

Thanks, OlympicMtnBoy (Toyota MH newbie)

Its probably OK. The Chinooks weigh far less than the 18 ft Sunraders. But if it has or has had the rear welded together dual wheels they created extra leverage (bending) of the axle ends and there could be some stress damage from that. That's one of the big factors that cause the rear axle breakage in the larger units with the stock (bad) pickup axles. They keep flexing at the ends right at the bearing and eventually snap off. But like I said, the Chinooks are far lighter. If it is a concern you could replace the axles with newer heavy duty ones and replace the welded together wheels with singles and higher weight rated tires and bee good, as long as you don't fill the back up with people or cargo to the roof. Maybe someone here who owns a Chinook will throw out some first hand knowledge!

Thanks Greg, it sounds like I'm OK since I have a light model and single wheels. I did some reading on the yahoo group and that seems to be the general consensus as long as I don't overload the thing. I do need to get new tires though. :-)

I think about the only thing that is safe without the good axle is the Chinooks but only if they are single rear rims and not dualie.

On another note I deleted some posts (4) in this thread. This thread is for AXLE questions and answers only. So please keep the off topic chit chat out. Sorry to do that but this thread needs to stay focused on axles.

did anyone ever get back to you about what makes yours not subject to the recall? I have a 1983 toyota odyssey and couldn't find a recall on it, but am still concerned b/c it is the old 5 bolt axle.

thanks,

Hi, I have a 1990 toyota and am getting work done to the rear axle, it is 6 lug. Long story short the mechanic can't get new axle seals from the toy dealer. He has had them bring him 3 different seals and they are all wrong. he gave them the vin and everything and they are telling him it is obsolete and you can no longer get seals for them. can anyone help me find seals or toyota part numbers for the correct axle seals? anyone ever run into this problem? Please Help

Thanks in advance

Try a local bearing company they will need the old seals for dimensions but they should be able to help you out most bearing outfits do seals also.

Hi, guys.

Just bought a 1977 Keystone camper on a Toyota chassis. It has the dual wheels and 5-lug axle and I am about to drive 12,000 miles in it, so I am pretty positive I need to convert the rear axle. I have been trying to find a donor truck and it's been hard. I am not sure I am asking the salvage yards the right question, though. As soon as I say what vehicle I have, they want to find an axle for that year. I have tried to explain what I need and I don't think it's working. That's probably because I do not know exactly what I need, either. So, does anyone have a tip on what exactly to tell the salvage yard to look for? Is there a year range on the donor vehicle? And did anyone ever figure out how to get in touch with Chuck Nan of the cheap conversion kit? Any tips at all would be helpful. I am also unclear on what I need beyond the better axle in order to make the conversion. It's a four-speed, 22r engine.

Thanks!

You need to ask for a 1989 or later year, full floating dual wheels. Make sure if you find one that it also has the wheels.

I found Sadie's 1ton at www.toyotasalvage.com in Phoenix AZ- Don't forget to ask them to include the brake lines and sway bar too.

Thank you, guys! Both tips should be very helpful, especially if I can get that one in Phoenix! Oh my God, if I can put this to rest this week, I will be so relieved. Thank you again. I'll let you all know, if I get it.

Hi again.

I seem to have found one through the Phoenix link but not at that company in particular. I got passed from one to the next till I finally found a guy, Dave, with a rear axle off of a 1990 Toyota, a one-ton dualie. It's got the brake line, needs new rubber pads, apparently, and also has no wheels, no sway bar. Total price with shipping to Georgia: $650-700. Does that sound expensive, considering I am going to have to get all that other stuff to make it work? Now that I know more what to look for, I could try again locally. Just thought I would get some input on the one I found today. I also thought I'd attach some photos of my current axle set-up, just in case you guys have any additional input after seeing these pics or if your input changes after seeing them. I'm really a novice, so I appreciate your help.

Thank you again.

MG

Hi, I have a 1985 Toyota Dolphin from National RV with the old 5 lug axle. Is this one one of the recalled axles and if so will they repair it for free?

thanks,

I am almost done my axle upgrade on my 84-85 Vangaurd. I used a 1 ton dually from a Chev van, and put lower profile tires... contact me if you want details. WARNING....IF YOU ARE NOT SURE OF THE AXLE ON A TOYOTA MOTORHOME.....DO NOT BUY IT OR EVEN TEST DRIVE IT. i ALMOST KILLED PEOPLE WHEN MINE FAILED..........

Please provide details. I'm sure more people than I would like to learn of this alternative source. Any info on what ratio you have in it? What are you using for rear wheels? I don't suppose the Toyota 1-Ton rims would fit a Chevy, or an I wrong?

Are you in Canada, given that the Vanguard is a Canadian MH.

Hello All,

First off, I'd like to say "Hello" and that I truly wish I had chanced upon this forum before I purchased my rig!! You guys know your stuff and I appreciate the effort you put into the site.

So, here's my situation: I have just purchased a 17' 1980 Toyota Dolphin with single wheels in back and five lugs per wheel, around 130K for mileage. I have read all the literature available on the rear axle issue and, after much trepidation, have begun to hope that the rig might be OK as is. However, I'd like to get the opinions of those more knowledgeable than I on the subject. I don't plan on doing any major driving for a few months as I work out some other (hopefully) minor details, and, during that time, I'd really like to put the axle issue to rest, one way or another. Any help you can give would be much appreciated.

Thanks,

Bonner

Take it to a scale and weigh it front, rear and total. Without that information all will be just suppositions.

Find out what Toyota says the rear axle max weight is and compare your numbers.

Hi All--\

I'm assuming a 17' Sunrader with a 5-lug dually is not a good thing--or is it passable? I've seen a "pass" on the Chinooks, but I don't think the previous Sunrader question was directly addressed, though the Sunrader is I would assume significantly heavier than the Chinook? The welded duals can't simply be replaced with a single, right? any idea what a single-wheel axle would cost, if I want to go with that, rather than the dually? The weight is in the wheels, not the tires, right? so it wouldn't help to simply take off the inner (or outer) tire?
