My 1983 Nissan 720 4WD looks like its sagging and cambering the wheels on both sides. Its eating into my tread like mad. I had to rotate my tires about 3 months ago. It took a little longer than that for the front set to first get eaten into. The tires have about 12,000 miles on them.

What the truck has:

• Stock suspension (Indepedent front with torsion bars)
  Stock 15" wheels
  Stock 4 cylinder engine

Any idea exactly?

A guy I used to work with had a nissan about that age. He has a similar problem. Does your sit lower in the front? The front end shop here cranked his torsion bars up..then did the allignment. That stopped his tire wear problem.

Apparently his was way off. They could not allign it like it was.

Ah. Yes it is lower up front. Well, my buddy tried to do me a favor earlier in the year by cranking up the torsion bars but his air impact gun rounded off the head of the bolt for the torsion bars. I guess I'm going to have to put on new bolts and thread locker onto the torsion bolts then. Sounds like great fun. Thanks for the input.

Brian is right....with age your torsion bars weaken kinda like springs do over time. But springs cannot be adjusted and torsion bars can....they will need adjusting and the front end re-aligned. Best to take it to a front end shop.
