Hi all,

I'm currently removing my standard Sierra back end running gear and replacing it with a 4x4 jobbie.

I've got it up on stands, got the rear brakes and driveshafts removed. Then I thought about the diff. Bugger, I didn't undo the bolts holding the prop to it!

Will I be able to undo the prop bolts now? (I torqued them up proper like) I don't want to put it all back together.

Have you got a compresor and impact wrench????

This will do the job no probs

This was how I did my donor car when I had it in the air doing the gearbox

Nope and nope

Put a lever between the propshaft yokes and undo bolts if you don't have a compressor /air wrench.

Try clamping some molegrips across the diff/propshaft flange (as if you're trying to clamp the two flanges together) and rotate the shaft till the grips meet a solid object, like the bottom of the chassis. Usually works for me.

Cheers guys, looks like I'll manage!

if you are still struggling Northy, I've just bought a compressor and am looking for a windy gun. You can borrow them if you want.

Cheers Trev,

I probably won't try to do it till next weekend now.

I'll strip the interior on a night during the week to get to the top of the prop
