Mark,

You are correct. There are at least three ways to tackle this job.

1. The sleeve you can buy is from the 78-89 Porsche 928 parts bin. It's a metal sleeve that you slide in place after you've pushed the deteriorated plastic (on the I.D. of the existing shaft bearing) down and into the steering column. This sleeve is part # 928 347 739 02.

2. The new bearing placed on top of the old bearing is good too. Probably quicker than #1.

3. Pull the whole column and replace bearing. This is your last resort. This job sucks. I did it and I don't want to ever do it again. Like you said, major PITA. Too much crawling under the dash and in the trunk. No thanks.
