What diameter torsion bars?

If the adjusters are in good condition you shouldn't have any problems. The threads can be damaged like any other bolt, and they tend to get exposed to a lot of crud. I usually spray some WD-40 or Kroil on them before I loosen them up, haven't had any issues yet. Biggest thing is not to adjust them while the car is sitting on its wheels, they can strip out if they're adjusted while under load.

Thanks for the info. I hit them last night with some Blaster. Figured I'd start soaking everything before it's taken apart/adjusted. They are just rust colored and look in good shape.

I was going to let the shop change them but considering recent bills I may have to do these myself. Doesn't look to bad from what I have read and I also have the shop manual.
