Ive got a 98 Opel "wizard" But in fact after some searching it is a Frontera body and settings I spoke to the previous owner a couple of weeks
ago and he asked me how the truck was going I told him I had 2 wheel alignments done because it seemed to be a bit heavy in the steering and bit on corners. He said he had 3 done while he had it and had the same problem
So this weekend I thought I will sort this First look at the Frontera book and the first thing to check was ride height. So had a look and the drive shafts were going up to the wheels and when you looked at the truck from the side it was down in front . 40mm out So jacked it up and with some CRC help, adjusted the front trim to the book
Man what a different truck, light steering, no bit on curves . So I think this is a regular check for me, say at warrent time
I stuffed up the data so deleted it Forgot about the tape measure width I will check it again next week when it settles down and do a precision setup with the right gear good rule, height gauge and venier

Interesting but just to make life harder that adjustment will of effected the wheel alignment. Probably only tow in though. You need another alignment.

I think that it's normal to get some suspension sag after a decade or 2. The front of my Jackaroo had sagged by 1.5-2 inches when I bought it, and the rear about an inch. To raise the rear end I purchased a pair of shock absorber overload springs, ( https://www.amazon.com/Superior-14-0890 ... B000CPJMCU ) these slip over the shock absorber and are held in place with a clamp on each end of the shock. Now the back sits about an inch higher than a standard jack. For the front I used a rattle gun to wind up the torsion bar bolts, and got back at least the original height, maybe an inch more. I did have a wheel alignment done at the sagged spring height, but it didn't steer very well even though the wheel aligner guy was constantly talking about how good he was at his job! Winding up the torsion bars bought the suspension geometry back close to where it was supposed to be, all I had to do was adjust the toe in a tad and now it steers better than it ever did. The book specs for the toe-in is about 1 degree toe-out, but this often results in tyre wear on the inside of the front tyres, along with imprecise steering, so I tried about 1 or 2 degrees toe-in which works really well. The car rides heaps better with the raised suspension. I recently got a new set of tyres put on it and the wheel alignment guy (a different one to above) didn't have to adjust anything.
