They say those really don't cause a problem.

Mine have never been changed.

The ones on the rear axle are the ones that go bad.

The ones on torque arms.

If your going to take torque arm off. Then yes put new ones on.

No, look at the ones at the other end of the arm from what you circled. But change those at the front of the arm also as they will be elliptical now instead of round.

The work at the back of the car is a little easier than at the front as the torsion bars are captive in the rear frame and can not unwind as they can at the front. You can unbolt the rear shock absorbers and the stabilizer linkage and let the the rear axle drop down as far as it wishes.

here we have pictures from rear, left side.

i find one part that looks faulty.(arrow marked in the picture)

That's the lowers. Replace with 55 bushings.

What is the copper line that is visible in the second to last photo?

What is the difference between 55 and 56?

i made order from steelrubber. I hope that these are correct.

Copper line is rear brakeline.

Stop. Yes the bushings you picture are for a 56 but I do not recommend them. They will last about a month. The 55 bushings have much more surface area to support the load. They will replace the ones in your r2 picture.

In your r6 picture there are many things wrong that need to be corrected before other suspension work is done. Your leveler motor has been run much too far: The connecting link between the leveler and the torsion bar has rotated towards the rear of the car. It should be toward the front, and the longer connecting link going to the right side of the car should be toward the rear. The short link also seems to be bent and should be removed and straightened. Notice also that the torsion bar arm has been pulled very far toward the center of the car. Normally this would make the back end of the car sit VERY low. Under most load conditions that arm is almost vertical.

The last thing I notice is that the small adjustable link that operates the torsion level control box is bent and needs to be straightened.

I fear a lot of damage has been done to your car in the past and it will take some time to repair all the details of the Torsion Level system one by one to make it work properly. Please be patient!.

The previous owner has changed the height adjustment to work manually. There are no wires in the controlbox or limit switches.

I need to make new wiring to this system.

Where i can order these -55 model bushings?

Are these bushings made from rubber or nylon? i can make nylon bushes myself if i have measurements.
