was going to change my diff fluid the other day and the head of the one of the bolts stripped. any suggestions?

 

die grind a notch in it so you can get a flat blade screwdriver in it then hit it
with a dead blow hammer and hit and turn tell it bust loose.

 

should i try a vise grip first?

 

Yes you can do that. If you have a welder, you can also weld a nut to the end of the bolt and then get a wrench on the nut.

 

Grind the head off the bolt, then use vise grips to get it out...after the cover is off. Or like said weld a nut to it..

 

If you just want to change the fluid, I'd take out the drain plug under the differential and then refill it through the fill/check plug (obviously haha). I didn't know these had drain plugs on the bottom till tonight when I put my TA girdle on and saw it under there.

 

if you are one of the lucky few that have a drain plug on the rearend.

 

Id try the notching it and use a flat head screwdriver... if that doesnt work, weld a bolt or nut to it and try that.. if thats not successful then just grind the head off and use visegrips..

 

If you have a welder....save alot of mucking around and just weld a large nut to it.
