so today since my truck is down for a clutch i figured id pull my third and weld my diff. well not thinking about it i pulled it out assuming i would just be able to weld it like all the pictures iv seen on here. well i have a 4 pinion diff so i dont have windows to weld trough.

So i would love any pictures or suggestions on how to do this if possible... and do i HAVE to take the ring gear off to split the two halves or can i just unbolt em and split em?

man I cant help you but can you take pictures of this "4 pinion " you have . My 94 is suppose to have 4:88 4 pinion and and my 88 has 4:10 2 pinion and I dont know the difference .Ive seen the 2 pinion but not the 4 pinion.

Thanks Man !!

my gears are 4.56 but that doesn't matter.

so I see the case part in the center is different , the 2 pinion doesnt have one like that. OK thanks a good luck taking it apart man !!

if you look in the FSM it will show you both types so you can compare them

so lets say i split it open and run a bead where i circled all the in all four spots. good?

i didnt even take mine apart. just took the 3rd member out and welded all the spots i could reach with the gun, then rotated some more and did the same thing.. havent had a problem in over 5000 miles. (daily driving, rubicon, snow runs.)
