So this is a shot in the dark, but I'm troubleshooting my GSL-SE and I'd like to swap in a different rear end for diagnostic purposes. Doesn't have to be LSD, just something that fits. If it's the non GSL-SE lug pattern, I'd need to borrow the wheels as well.

If you have one you could part with for a few days or know someone who does, let me know.

 

Do you need the whole axle, or would just the center section work?

 

Perhaps describe your issues/problems and we might be able to help you avoid a lot of work :-)

 

Center section? You mean the diff pumpkin? Probably better to just have the whole rear end.

I'd like to avoid the work myself, so I might start by pulling the axles out and seeing if they're bent.

 

Have you pulled the driveshaft and checked that the u-joints move smoothly and freely? Sounds to me the most likely cause.

Remember that a driveshaft vibration will be at engine speed in 4th gear, an axle vibration will be much slower, i.e., wheel speed.

 

ive got one, but id rather sell it then let someone "borrow" it. its a gsl se rear end with a 4.875 gearset in it.
