Ron,

I just completed the same job on my '88 740 GLE, 155k Miles. My experience with the job is a bit different that the other posts and I'd be glad to share it with you. Actually, I wrote down the entire technique, and was planning to submit it to the Brickboard for publication, but got distracted. Anyway, I did the job without benefit of a hydraulic press, and you might be able to do the same. I agree that taking the shaft to a shop with a press is a good suggestion, but I did find that I could do it myself. I can email you the procedure if you contact me at MANNDL@yahoo.com. Depending on the driveshaft you have (there are two different center bearing shaft diameters, mine is the smaller of the two) you can use a 12" piece of 1.25" galvanized pipe that you can buy at Home Depot for a few bucks to drive the bearing onto the shaft. It fits nicely over the shaft, and neatly on the inner race of the bearing, and worked well for me! The job took one day, and the most difficult part in my opinion was removing the old bearing and center support from the shaft.
