Title: Drive Shaft Swap
Post by: ivanidea on March 04, 2015, 04:23:48 PM: Hopefully, we will get some dry weather this weekend, so I am planning to replace the front offside drives shaft in the TJ, since I've been told it's a simple job.

Any thing I need to know, be aware of or just general advice?

Have you found a decent How To? Everything I've read says it should be pretty straight-forward. Have you got a big (36mm?) socket for the axle nut? I'll be covering the axle in penetration oil a few days beforehand, apparently seperating the hub and knuckle can be tricky.

Get some plus gas/wd40 on the 3 bolts that hold the hub to knuckle, today more tomorrow then on Friday, unbolt the bolts half way give them all a tap from the back, then thin cold chisel gently working round the backplate to separate hub
When loose remove bolts then pull out shaft.
I use a Henry Hoover to clean dust out of tubes so new splins don't push old mud dust grit etc into diff.

leave the bearing on the shaft - you don't need to remove it to do the diff - in fact I've changed UJ's with them on

Plus as it isn't your daily driver if a bolt or something breaks you can probably reassemble it most of the way and then get a replacement from one of us by post - I've got loads of odds bolts lying about and I know Tony is the same.
