996 Alignment

[shark715]

Does my '04 C4S Cab require any unusual equipment for an alignment, or can I expect that any decent shop with modern alignment equipment can do the job correctly? Thanks in advance for you help.

Any decent shop should be able to do an alignment, be sure they have the right specs for your type car/suspension. Do not forget to top up the fuel tank before the alignment take place.

On 4WD cars the steering angle sensor should be checked at each alignment (or suspension change).

Thanks, would a typical alignment shop know how to check the steering angle sensor, or is that going to be a job for a dealer and/or Porsche specialist?

A shop that works on Porsches (or other 4WD) vehicles should know how and have the equipment. Durametric, a PST2, or PIWIS tester would be needed to check and re-calibrate if needed.

digging up this old thread as after changing the inner and outer tie rods and strut bearing on my C4S, and getting it aligned (not at the dealer) I now have the PSM and ABS lights on. Why would only the AWD cars possibly need the angle sensor realigned? I'm just trying to understand how this system works, thanks. I've never had any issues with alignments previously.

Your PSM and ABS lights should go off after 5 to 10 miles.- if they do not then you have a problem.

Driving for more than 10 mi. didn't do it. I was hoping for more "tech" in an answer, but anyway it's fixed. After reading various forums I came up with a list of things to check and did the following: Disconnected the battery and put it on a charger. While the car was starting up fine, I had been working on the drivers side window mechanism the day before, running it up and down a lot. I also pulled out the front ABS wheel sensors and sprayed them down with brake cleaner, and did the same with the ABS rings. I also wiped off the electrical plugs and really made sure they were plugged in tight.
