Center Bearing Replacement


I am wanting to replace my center bearing and front/rear flex disc in my 85 300D. I have a hum that I strongly suspect is coming from center bearing. But since I am going to have to pull the driveline, I was thinking it would be a good idea to replace flex disc while I am doing the center bearing job.

Can someone give me some tips or tricks to make this job smooth? I am a confident DIYer and have access to auto hobby shop at my AF base with lift.

I would appreciate any comments and how long I should plan for this job. I have already ordered new flex disc, center bearing, center bearing support and bushing, and new shaft bolts from Fastlane.

I did this job on my old '71 250. I didn't have to remove the whole drive shaft. I simply disconnected it at the tranny end, undid the bearing carrier from the chassis - and here's the iffy part - I used a Dremel to cut through the old bearing carrier and bearing. Since I was going to replace these anyway, I saw no reason to keep them. I actually stopped a few mm short of the actual shaft and used a hammer to snap the bearing off so I wouldn't damage the driveshaft. Once these had been cut through, it was easy to slip on the new carrier and bearing. I'm not sure how different your driveshaft and components are but they should be similar. It might be worth looking into - much easier than dropping the whole driveshaft.
