Unable to get proper rear toe-in alignment

[Thomas Owen]

That must be a relief... Call Parts Heaven, they should have one.

porta-power the lower shock mount until the alignment comes back. You have to go to extreme measures to repair bent Porsches.

Great idea. And while you're at it Porta-Power the front shocks mounts together to get some extreme negative camber. Who cares if the hood gaps close up?

Its just a bent part, not a bent Porsche. The t-bar tube, frame, trailing-arm brackets are all in spec. Replace the part, fix the problem.

The rear suspension is from a Carrera and was installed by the PO. It was most likely bent when he installed it. There are no signs of crash damage on the vehicle.

Mike: If the arm is not too much bent, some heat and a little pressure could bring it back. Otherwise, I would prefer to stay with the right size bolt and file out the hole.

Or you could just attach the front fenders with spacing washers and pull the towers together with a strut bar like the F Stock guys do.

You haven't worked on many bent Porsches.

to my understanding the rear control arms are designed to be flexable.. meaning that it's not being stressed for small adjustments like Otto performs.

Otto;
I'm just trying to picture the details of what you described without doing something stupid like I usually do.

Option one: Brace axis of the spring plate (through the access hole) up against an immoveable object. Then use pull the lower shock mount out until the car aligns This will basically pivot the triangle created by the banana, spring plate out around the front pivot point.

Option Two: Push the lower spring plate out (by pushing against what???) to accomplish the same result.

Any good ideas that people have used to brace the car without resorting to a complete alignment table?

Half an hour on the frame rack cured it and dialed right in afterwards.

What does half an hour on a frame rack cost? Can it cure anything?

when my car was aligned the front camber was just on the edge of being in spec, and they said the front shock towers over time move sag inwards.

[Mike Bonkalski]

Is it worth it to try bending the control arm if everything else is in spec? How long would it take a shop to do this? I can just buy a *new* used arm for $100 and install it myself.

Mike, just buy a good used one. Doing anything to straighten the arm while it's on the car is likely to twist or bend something else. Your chassis is straight...do fuch! with it.

EASY has a good rep.

Hi Bill:

Mine was an easy fix. Somewhere in the life of the vehicle, it took a hard hit to the left rear wheel and bowed the rear torsion tube to the front of the vehicle. The guys with the frame rack were able to pull the tube back in position. It was straight forward, although they were really surprised how much force it took to do it. They honestly thought they were going to break something on this "fragile" car. Remembering that I live in a small town in Northern Alberta, the whole thing cost $75 cash and a six-pack of beer.
