is the 85 rear weaker

[sammy 87]

is the 85 yoda truck rear any weaker than an 87 and why my friend has an 87 and hes big into his truck and he told me the 85 rear end was weaker than the 87

The 85 and earlier rear housings are 3" shorter (1.5" per side) than the 86+ rear axle. Aside from a slightly smaller housing thickness it is not really "Weak" until you start pushing 37+ inch tires and lock it. Unless you are planning on running 37"+ and also planning on beating the crap out of it, it is not worth swapping unless you want the extra width.

true that, also its not in a book or proven anywhere but I think the shorter shafts are harder to break, think about it. To me theres less leverage to be distributed through out the shaft.


And, if your building a trail truck and need tight technical I think that rear is a viable option.

I don't think the axle shafts are any weaker, although I do see the point about the length, very slightly less torsional loadup on a shorter shaft.

Besides the length, the brakes are significantly better in the 86+ axle. Drums are larger, e-brake setup is better.

Oh yeah, forgot about that. Better brakes for that big rubber. If running small tires though the difference is negligible.

Isn't the difference 1"?, bigger diameter?

Yeah if I recall correctly they are 1" or maybe 2" larger. Not a lot but you notice the difference with big tires.

 

[KLF]

They are bigger diameter, the shoes are wider, and all the linkages in the drum are a better setup. The pistons in the brake cylinders are a little bigger too.

thank you im just thinking about runnin max 33's thats big enough for a sammi

in that sense it would be even stronger as the vehicle would weigh less.

for a samurai the stock 79-85 front and rear axles will be perfect and you wont need to run spacers to match the front to the rear.

any body got a good idea about making the stock tcase or a tcase work i found a place that sells a plate and yokeplate connected to the tcase plate to make the toy tcase divorsed but its like 550.00
seeing how the sammi case is off set to match the rear do you guys have any idear to make something to work with yodas since its centered and the sammi is pass offset rear???

 

[tntoyota]

Are you wanting to keep it Zuk powered?




I always thought if I got to your point I'd skrap the sami case, (No practical experience here) its a little far back aint it? I'd go Toy 5sp and TC. If the axles where Toyota, a tranns/ TC is not hard to find wouldn't the Toyota motor would be a power increase?

Can you clock it maybe?

Just fab some shifter linkage.....and TC mounts....????

ive thought about the yoda tranny and tcase setup but id want to either put in the efi 1.6 and i dont thing they have a yoda bellhousing adapter the 4.3 i think they might my friend with the yoda truck wants to use a 4.3 and his yoda tranny and tcase so if i do any swap and yoda tranny and tcase i think id use the 4.3. the divorsed tcase i think gives you more options since its not bolted to the tranny

I dont think that TC is as strong as you think....:whoops:


Whats your build plans?.....or blueprint?

rocks?
trail?
44's?

350?

what?

 

[sammy 87]

well idk quite yet im waiting to see if the geo tracker tcases flanges are the same size as the sammis. if so il use a 1.6 geo motor tranny and tcase since its center out put and i got a good price from a friend for front and rear 85 yoda axles. thats the plan so far it aint much but its a thought.
