Diff Question

[mgbrv8]

I took my differential down today to inspect and clean. I had alot of red silicone in it, over squeeze and loose particles and I didnt know if that should be a concern or not. Do you guys have any suggestions or mods that could be done. I am happy with the gear ratio. So far I am just going to change the seals but any other advice would be greatly appreciated.

I just got done removing my differential for a gear change, and the red silicone everywhere is the norm, not a whole lot of care went into putting that stuff on from the factory. Here's a pic of mine when I got it apart.

Is there any shiming that can be done between the cover and retaining caps to siffen things up.

Dave

Wow, I am dropping mine today too and I am sure mine will look like this too. I am doing a total rebuild with 4:10s and the only other mod I will be doing is using the studs instead of bolts for the caps.

I have a question. Why bother going through the trouble of machining the bearing caps so that the cover provides some support and then goop it all up with silicone. Since there is silicone on the caps the cover cant be supporting them. Would it be better if we used something like the sealant on the cam covers?

Were did you get your studs? I was also looking at machining the case so I could use the bottom bolt as a drain plug. I was also thinking about drilling and taping the stand offs on the batwing and place some allen screws to preload to supply more support.

Is the GM service manual for a zr1 different than a regular 91 vette?? I see the Lt5 supplement all over ebay and no ZR1 manuals.

There is no ZR-1 model specific service manual that I know of. Most topics are addressed for both standard and ZR-1 models in the regular GM service manual. The LT5 supplement addresses the LT5 specifically.

I have been looking for or equivilant GM sealent for the rear end #9636067 and none of the parts stores can cross refernce it and the dealer dosent show it. Is it a silicone or ureathene? Any imput or experiance on this would be appriciated?

Dave

Dave, I use a sealant called "The Right Stuff". Use it on LT1 intakes and LS1 stuff and have never had an issue with it.
