I've read elsewhere that some installs require shims and some don't. I can't explain it. Make sure youre suspention has settled before you try to allign it.The car will not allign or keep an alignementif the suspention has not dropped. This is different than most any other car including other porsches.

Absolutely! For those of you who may be following along and had not ever heard of this FACT before, be advised. The front end bushings in ALL of these cars assume a "set" position once the car is lifted. It takes as much as a couple hundred miles of driving for the suspension to return to its normal settings. For this reason, it is often very hard to find shops who are willing to align the car because this pretty much eliminates the "shake down" process where the quality of the suspension parts are inspected prior to checking the adjustments. The 928's suspension must stay compressed during the initial inspection.

I have heard the same.
If I get a chance, I am going to see if I can devise a process for setting up my own alignment with out having to buy a lot of expensive equipment.
Maybe this winter I will get a chance to work it out.
If I forget, remind me.

There is a write-up for do it yourself alignment, using some reasonable tools. It was on the list of tools for the 928 OC to have, so it could be used at events put on by members. I could dig around for the information, if that would help.

That would be great if it is different from the link Austin posted

Thanks Austin, great link, I can't wait to go through the procedure.

I expect it was Earl I had it from, so likely the same information.

What is this steering rack center bolt that I see talked about?
Is it the lock on the steering column or is it a line up hole on the rack?

I have the bolt, and presumed it fit into the rack body.

The steering ract centering bolt centers the rack and locks it in place. This will ensure equal turning from side to side and allow you to center the steering wheel ont he splines of the column. It's only a few bucks. I know 928 Specialists carries it and I assume other vendors do too.

For home alignments, I will drive the car up on on ramps so I can install the centering bolt, and loosen the tie-rod nuts (sometime you need the extra room to break them free). Then back the car off the ramps and proceed with the alignment.

BTW, I did a video and created a spreadsheet to do your own alignments. It's a bit rough, and I plan on re-visitng it one of these coming days to make it more user friendly. Hope it helps.
