Causes of Steering wheel play?

Easy test is to have someone move the steering wheel within the "slop" range and inspect the bits that are moving and aren't moving. The coupler from my intermediate shaft to the Rack was loose so it was slopping back and forth within the gear giving me a really nice dead spot in the steering wheel.

I dug up an old thread that Van started on rebuilding these units and asked if he ever did rebuild one.

When they cost $150 new, it was a wash. Now, the part 944-347-027-02 is no long available from Porsche.

I realize this is an old thread, but I'm having the same issue. I have about an inch of slop in the middle of my steering after replacing wheel bearings, tie rods, rack bushings, steering rack (rebuilt unit), and intermediate shaft. I have to turn the steering wheel about an inch either way for the steering to "catch" and move the wheels. I did check the rack for slop and didn't find much, but I did notice slop in the new shaft u-joints (as seen in the video below). Are there multiple suppliers of new/rebuilt intermediate shafts, or has anyone had luck in modifying an OE manual rack shaft (I think these are still available, but pricey)?

Rennbay have new shafts for a power rack, the manual have been nla for some time and besides they don’t fit and are imo dangerous to modify to fit.

I do have a new shaft for a power rack, but like the video clip (video is not mine), others have experienced the issue of play in these new u-joints. I initially put this shaft on my car last summer and have been chasing down the slop issue by replacing everything in the steering system that could affect this. From my analysis, this joint (even though new) is likely my culprit. I'm just wondering what my options are, beside finding a good used one.

Thanks for the advice sherry66, I just receiving my LHD steering shaft from JMG Porsche. Luckily they had a LHD shaft in stock and ready to ship, as you normally have to send yours in for rebuild. The joints look to be very nice and tight, with no play what so ever.
With a steering rack lock bolt in place, it appears that I also have excessive play in my steering rack (in addition to my shaft play). This is unfortunate because I just replaced that rack last year with a unit rebuilt by Detroit Axle (bought 2nd hand, but never installed). It's never leaked, but not tight enough for proper handling. Any recommendations on a reputable steering rack rebuilder (from experience)? Zims, etc?

Fast-forward 15 years (!) from the original post. I did replace the u-joint, front bearings, rack mounts, etc. over the years and the steering slop did get better compared to 2005. That said, it still was a little sloppy and I couldn't 'see' any slop when I'd check it. That slop virtually disappeared overnight when I installed KW coilovers. The old struts were just completely shot, and were apparently contributing to the slop. Just one more thing to consider if you are having this issue....
