Finally got the front end completely apart and found a couple of interesting things, including cracked torsion leaves; bit of a bummer as all i planned to do was rebuild the brakes calipers and replace the ball joints. But what I'd appreciate input on is related to the torsion arms which I've found to show considerable wear at the location of the inner bushing. I've attached four images of a typical torsion arm. The first is from the top and shows little wear - great! But the last three are taken of the underside and show considerable wear at the inner bushing location. Funnily the outer bushing seems to be wearing very well with it still being very clean and smooth. I note Bentley states the inner bushings are usually a low wear item, but then who knows jow many k's any of these kombis have done. I would have thought this is a sign I need to replace the torsion arms and change out the inner bushing and outer needle bearings as well. The problems of course being, you can't buy new torsion arms and the bearings are a giant pain to replace without specific pulling and install tools. Or perhaps I'm jumping the gun? Am I right that the arms are shot, or would they and the bearings still be ok for a fair while and I can just put back together pleading ignorance? Or are they at a stage that I should try to source replacement arms and go through the pain of replacing the needle bearings and inner bushing now, particularly as I've come this far. Any tips on where I could source used torsion arms in good condition, and also tools to pull and install the new needle bearings and bushings? Do I need to get a machine shop to fabricate tools required?
