I just got a 82 GSL rear end to swap into my 83 project car, also picked up the 82 driveshaft that I'll need as well. I figure while its all apart I'll change the u joints, but I got a dumb question, are both the front and rear u joint the same? are both replaceable? I would think they would be, but just want to check before i order parts. Also, any thing I should be careful of when changing them? TIA

anyone?

 

if my memory serves me correctly they arent the same, but they are both replaceable

 

Both of the U-joints on my 79 driveshaft were the same. and im pretty sure the driveshafts are the same.

 

'82 and older are replaceable and the same front and rear. The '83-'85 are not replaceable. I don't know exactly when the diff flange changed (became larger), but it was right around '83, give or take a model year.

 

The flange changed in 83. So, 79-82=small flange; 83-85=large flange. The axles size change happened the following year, in 84.

 

what do you mean you cant change the u-joints? ive changed mine on my 84....and i just got an 85 drivshaft and im going to change them on it aswell...and both the front and back should be the same...

 

ok, so i gotta order 2 of the same u joint, sweet, thanks guys.
