So where to begin? Just bought a Toyota 1984 mini motorhome 22r 2.4L welded extended frame , turns out that it's got the death dually's , it only has 60,000 miles on it and it looks like the rear end is just been serviced new brakes , sealant on the differential cover ... Huge leaf springs since the air ride blew out .

So I have a 1995 4Runner in parting out and the frames almost the same , I'm thinking grind the old welds remove the 84 reared and weld it in so I get the 6 lugs anti sway gear and slap some air ride in the coils , and finally get rid of the dually rims , what to do...

Death dual`s first I heard that care to elaborate ??

Just what don`t you like.

This is after all your project you have your work cut out .

Just get everything on straight and level .

It is a real pain getting a spring pad on crooked and having the axle housing crooked

Oh I see you plan to keep the coil springs that will be a trial and error project till you find the proper rate springs the 4Runner ones will have the back end so very low I am sure you have some good ideas where to start

Unless your planning to run a complete air ride system compressor bags and valves.

Should be a intersting project.

So my campers one made by coach builders who bought the Toyota pickups with out the bed , cut the frame in 1/2 added about 40 inches to the middle and welded an extension on the back as well , the weight was too much so to meet road standards they welded a outer ring on the tires so you could bolt two together , the front has 2 bearings the rear has 1 , no clips in the axle so when loaded the putter wheels press on the inside of the bearing instead of evenly distributing the load , and when they go , tires breaks and all go loose , nice feature when there's a lp tank right next to one side and the fuel tank on the other .... So I bought one not knowing this , that happened to be built by a mini motor home company that the recall put them out of business and it never got fixed . Toyota offered a replacement for 3k back in 1985 was a fortune plus they had to install it free of charge . So Toyota dolphins made it thru but this is why they don't make em anymore , the rv manufacturers were giving toyotas a bad rep even tho they were modding inappropriately, it still has the Toyota name right on the grille so they refused to sell them to the rv builders and here we are ... I was puzzled and said the camper trying to figure out how to resolve all the issues ahead and I realized scrap it out and start over since everything was done so poorly,

Yes I'd like air ride in the 4Runner coils , that should do it , plus I'm going pretty light on materials , got everything out from under the body , putting propane tank on rear deck and waste tanks in the floor posting more tomorrow

Any full floating rear axle has the same set up.

If the bearing fails it all comes apart .

If you were close I would love to buy that axle .

I had one from the around that same age the axle had well over 1/4 million miles till I sold the vehicle now up in Vermont being a woods truck as far as I know

In any case good luck

At least they have c clips in there right ? And a 2nd set of bearings ...vs the single bearing I've got now ? Yeah 1/4 million miles sounds like way further then I'll ever have this ride.... on a what ? Not a 22ft 7 ft wide 6000 lb motorhome ? If so forget it I'll leave them in ... But I'm not opposed to running it up once I get my rig set up I'll be takin it out on a lot of road trips

Nope no Clips

just one wheel bearing !!

Unbolt the axles you can remove them

I never saw any rear axle that had more then one bearing

miketheband

So why the recall , was it actually the welded dually rims that made the bearings fail ? Is it worse to run it with the dually rims then just a single tire ? And yeah it's made it 60k so far as is .., so with maintenance it should be fine if I just swap out the bearings every 20k and I'll feel them on long road trips to see if their warming up , or jack the axle up and spin a tire ... Just want peace of mind

Here she sits now , how much play is normal in the timing chain ? Guides are ok and it looks like the head was redone .

I see now after doing some research If you have the old style 5 lug axle that Toyota more or less just added dual wheels .

I had the upgraded full floating axle that was built to handle the heavier loads .

Then with the way parts are swapped in these trucks .

Just what axle do you have the full floating one where the axle is bolted to the drum??

The reason for the failures was the early axle was not designed to carry the load of the Motor home in the unloaded condition load up your personal gear it was really over loaded. As these had the sealed bearings no way to check them .

Now swapping in the 4 Runner axle is not really going to gain you anything if your planning to use this to live in.

Maybe a Ford or Dana axle not real sure what kind of budget you have.

I don`t remember ever seeing one of the early axles .if I did I never took notice.

Not Toyota coach builders did the Jerry rigging giving Toyota a bad rep so they quit selling the cab and chassis ....,

It's just a 5 lug and the bearings for the 4 runner 6 lug are the same size so I know I'm not really gaining a lot other then heavier tire capacity , but I like the anti sway gear and the beefed up frame , I loose leaf springs but I'll put in a air ride

miketheband

Pretty rickety

Cut the welds and she's loose
