Differentials on 80's...shimmed or something else?

[Rusty Marlin]

I'm researching diffs for my build and the instructions mention adjuster nuts. I assume these take the place of the shims that are used in US designed diff builds and the diff is jacked into proper backlash vs shimmed into position?

If that's the case are there also locking nuts that jam the adjuster nut into final location, just like setting preload on wheel bearings?

Yeah basically. Carrier preload and of course pattern adjustment/backlash on these 3rds is with adjuster wheels, they have slots in them for tabs to lock them in place.

Heres a useful page with a million pictures and tons of info.

Yup, I see it now. That makes a lot more sense than the US design.
thanks

its actually and american design, ford 9" and all early gm dropouts have the same adjusters,

the toyota diff is a licensed copy of a gm truck differential. from the 50"s......

the dana shimmed diffs and the later gm stuff is just easier to put together on an assembly line and cheeper to build..alot less machining...

Yup. Landcruiser used that same basic diff all the way back to the early FJ 40’s.

Rear uses carrier bearing shims. Front uses spanner wheels

Only the locked third uses the shims, unlocked are all adjuster wheels. Could just Lincoln lock it, then it wouldn't have play!

Shows you what I know. I thought the 9.5 rear was a shim job.

Oh so that is how you do it? No wonder I could never get my lincoln lockers to work. lol

Like was said, only the 9.5 elocker, at least in the LC world. The 10.5" from a Tundra uses shims for some unknown reason.

oh great now I will have to look at the Tundra one I bought sitting on the bench to see if its 10.5 or 9.5

The shim setup is more durable, stronger, carrier preload stays tight longer.

Interestingly, I did a paper back in school on the Prius.

Found out Toyota owns the most patents among international patent offices of perhaps any other auto manufacture. I think the number of Patents secured by the Prius development signaled a massive struggle. Where other manufacturers were typically seeking patents in the international offices to the tune of a few hundred a year Toyota was applying and securing thousands. It was an incredible coup by Toyota. Master stroke in the world of long term revenue. Toyota absolutely cornered a lot of manufactures.

In turn, especially where fleet CAFE credits are concerned, Toyota sells CAFE Credits on the secondary market so that in part ‘dirty’ corporations operating in the United States do not get dinged by the EPA.

...but yeah, their cooperation with BMW in R&D, production is directly tied to BMW trying to avoid licensing development patents from the Prius. Don’t hear too much about BMW juicing their rides with Hydrogen anymore.

Is this just anecdote?
