ouch, BTW, with a r154 and 4.30 the speedo is saying 70 and the rpms are around 3300. also 110-115 is about the top of 4th.

an how do I tell what differential I have.... etc.

Your profile confuses me. It says that you have a 7M-GTE 1990, but with a W58 tranny... Was it once an NA? Or does it actually have the R154? If it came off the dealship as a 1990 turbo then you have a 3.73 (Could be 3.71, can't remember at the moment) rear end. If it came out as a non turbo, then it could either be the 4.10 open dif (only one tire spins when you do a burnout) or the 4.30 sport package LSD.

N/A's had 4.30 differentials, whether open or LSD. At least in the US.


Willfish, so the two bolts which secure the diff to the subframe are spinning? Sounds like the nuts inside the subframe broke loose from their welds. It's happened before. The last time I recall it being mentioned on here the owner had to cut a large hole (approx 1"x1") in the subframe so he could secure the nut. I think if you drilled a small hole offset just enough you might be able to wedge a screw driver in there to hold it in place. I'd at least try that before making a larger hole.

i might have clicked something differnt by mistake... it was manual transmission turbo out the dealer...
if I dump the clutch to lay tire, both tires spin,,, so you tell me what i got since I dont know.... how can I tell ?

sounds like I'm fucked them, from what your saying ? fuck !
Any work on how to get the axels off the differential, ? I got all six nuts offf ? another question,, is there 2 nuts, or bolts/ nuts at the top of the differential by the fuel filter that need taken off,? they seem impossible to get at with a socket or wrench....

You have a 3.73 LSD.

lol,, ok, cool, , ok, got any advise on my differential dilima ?:biglaugh:

Got a torch ?

Got a torch ?

for ?

to cut off the 2 that I thought i stripped ?

I've got my own problems with stubborn bolts not wanting to come out. The one in question sheared off and I'm in the process of drilling it out, but it's one tough ass bolt and it laughs in the face of any drill bit I throw at it... Believe me, if I knew an easy way to get one of those out, I'd share!

 

[willfish]

a co worker suggessted this,, ,, what all do you guys think ?


maybe on the opposite side of the cross frame member,, cut a whole in it large enough for a wrench. then obviously put that wrench on the nut that someone said here busted off from the welds... to get it off, an re bolt after swapping out the differntial..
then .

after swapping ouit the differential, get a piece of metal an weld it over the piece i cut out.....

what all you guys think ?

Will

 

[starscream5000]

Make sure that there's actually a nut there before you go cutting. I'm not sure, becuase I've never dropped my pumpkin, but just confirm with some of the guys on here that have done it and have had similar problems.

according to CRE there is....

Someone just went through this. IIRC, he said that when he cut the frame open he found that the nut itself wasn't welded down, but there's a metal cap that holds it in place which is supposed to be welded down.

If you're going to be cutting the frame, I'd go and just weld it back in place from the start... provided you've got the tools. You're going to need to weld it back in place anyway (unless this is just off a parts car in which case I'd just pull out the angle grinder).

angle frinder to cut the hole right ? my buddy has a spare supra for parts...,

That'd work, I just meant to cut the bolts off though.

well, I bougfht a cutting wheel for my dremal... I guess alot better than a angle grinder,, specially to get in small areas to cut a 1" x 1.5" rectangular hole..
on 1 side there is this covering folded box looking cap like I believe you said, ,, i think it was welded to the cross frame, so I had to bust it loose...

, does any one know what the size is of the nut... ,, would really appreciate it...

cutting wheel on a dremel doesn't last long...
