Torsion bars level problem-please help

Torsion bars level problem-please help

Postby martin.kryjom [OP] » September 22nd 2018, 4:49pm

I have read all posts on this forum acording torsion bars and I can not find any solution or explanation to my problem.
Im rebuild my Van for a last 6 months , almost everything is new, like whole new suspension from Moog, new pic steering pump, new brakes, new red head steering gear box and so on.
I also have a lift 2' , body spacers from overland.
My problem is that after we have change the whole front end I have notice that the driver side is much lower then the passenger side.
I find out that mechanic made mistake and pull off old lower arms without relaxing other end of the torsion bars ( "The Key side) So I ask him to do it again , but this time to relax the screw on the key side and pull the key off so the torsion bars are settle in a relax position. Then put the key and the screw back together .
So it did not help too much. I still need to crank leg side to 12 turns and right side to 8 turns only to get leveled front.

Is this difference normal?
Also Van is seating a lit bit too low as it is after 2' body lift on the high of 31,4 inch from the ground. In the beginning was 29,5 so there is a 2 inch difference ( so looks ok)BUT I put the new 235x70x16 tires opposite to 225x70x15 so the distance should be at least 0.5 inch higher

Other thing is that I have a problem with camber- to make it 0, it is on the minus side ( -0.1) , and the caster is also very low , somewhere between 2.24 ( I have read that should be around 3.5)
It shows that front suspension is still too low ( this is why is minus camber and low positive caster )
I still can crank the keys but why is the difference between 2 torsion bars torsion? ( why one side has 12 turns and 2nd only 8?)

Torsion bars are springs. They do wear out.

Well, I forgot to tell that my Van has only 32k miles. She was in Japan since the beginning, converted to "camper" van and then for 10 years unattached.
No rust, perfect interior, but looks like abandon :)
So I think it may be not the issue in my case

Crank one side up or the other side down until they match.

This what I did but this is just a solution but what about tech reason? Only age and wear?

Forget about how many turns, other than to keep track for reference and adjust to level, or close.

Similar to adjusting a car on coilovers to set ride height or corner balance, they are not going to be located the same on the threads.

Mine did the same thing. Of course, I just used a impact wrench to raise and lower them until they were even. The van doesn't weigh the same amount from the centerline on each side.
How many sensors, fuses or computers does a Bw4472 need? Zero.

Be sure to align your torso and noggin for maximum crush under the van. :whack:

I read something like this and just imagine some noob getting flattened. Horrible advice both from a safety and technical stand. :2:

Is this dangerous because the tbar could snap and the van would fall on you or...? Unfamiliar with what the dangers are with this.

BINGO

When properly done the T-bar bolt can be turned with your fingers.
