Torsion Bar Removal - Rusted
I am trying to remove the torsion bars from my 1994 4x4 S10 Blazer (4.3 L W-engine code/ 4 door). They are rusted and seized in both the lower control arms and the torsion bar adjuster devices. The torsion bar adjusters are mounted inside of the cross member which is mounted to the vehicles frame.
I have removed the bolts that connect the torsion bar cross member, to the frame on each side. I was hoping that would give me more play to loosen up the torsion bars, but it did not really help.
After struggling for a bit, I saw that there is a large dimple in the butt end of the torsion bars, inside of the lower control arms. I am thinking that I should be able to insert a long piece of rigid pipe into the dimple and hammer the torsion bar backwards to get it moving inside the control arm. Usually the torsion bar cross member would prevent this idea from working, but if it is disconnected, then it should float freely.
There may be some interference with the exhaust system on the passenger side, but getting the control arm moving is the main goal right now. After I get the torsion bar moving in the control arm, then I can worry about getting it moving out of the cross member adjuster. Will this work, or is there something wrong with this idea?
The rigid pipe is long enough that I can hammer in front of the vehicle and swing hard with a large heavy mallet. A friend will be able to safely hold the rigid pipe inside the wheel well with no danger of getting hit by the hammer. I try to avoid putting heat to my components but that may be a necessary evil this time around.
The usual instructions say to move the torsion bar forward, drop it out of the adjuster. Then move the torsion bar back out of the control arm. Of course this is if they are not seized... lol
I will be trying this tonight. If anyone has any suggestions, comments, then please let me know.
