I'm going to have the whole of the front IFS off of my 92 pickup 4x4 disassembled, anything you recommend I replace while it's off?

Here's the parts I've got so far:
new torsion bars (saw's)
new ball joints
new tie rods w/ sleeve's
new-ish a-arms (mine were rusty)
new rotors
new pads
new steering stabalizer (OME)
new wheel bearings
and some sway bar disconnects

 

You might want to replace or rebuild the idler arm as well. They're not that cheap to buy new, but replacing the bushings is easy to do.

 

forgot to mention, i have a new one of those as well

 

New shocks?
Ball joint spacers? (since you're going to be so torn apart anyway)
Clean, clean, clean.

The only other thing I did on mine was the control arm bushings, but with your "newish" arms you may be good to go on that score.

 

throw it away and hang a solid axle

 

if only it were that easy....

 

anyone have problems with steering spindle bushings?

im wondering if i should bother with them as precautionary maintenance

 

I replaced mine last year, I had a constant kind of scraping/grinding noise, especially on left turns. If you're taking the spndles apart you could look at the bushings, mine had very noticable score marks on the inner flange, where it contacts the axle. It would definitely be a good time to replace them, if there's any doubt about their condition.
