his sages- havent communicated a problem lately. my 92 245 with 5 speed manual has developed a very occassional shudder or vibration when i let the clutch out in 1st or reverse. it doesnt happen very often , only after i have been driving for a while and the car is hot. although the clutch and trans work fine , i initially thought it was clutch chatter, but have seen that before in american tanks and it has always been continuous. got under the car and suspected the ujoints of which there are two plus a rubber disk connection at the end of the transmission. these 3 parts are good andtight no sideways movement when pulled. think those three parts are ok. there is also a part i havent seen on rwd american cars. looked it up in the bentley and it is called the center driveshaft support bearing. it is a bearing which sits in a large rubber grommet in the cross frame support . it moves up and down when tugged and a little side to side. suspect this is the problem. problem is im not sure how much movement this part is supposed to allow. if no movement is allowed as in the spider ujoints then i guess it is the bad guy. if one of you has done this job please advise . also is this a common part available at a placelike autozone. volvo is the only car ive seen that has this. should i expect to pay fat dollars like at a dealer? thanks tons oldduke

Oldduke-

here is a helpful tutorial by Tony on Art's pages-

You can also look in the archives as I remember reading about if the bearing is the problem (and it's not on it's last legs) that some were having luck with pulling away the rubber carrier/donuts from the bearing and piercing the rear thin plastic on the bearing with a grease needle/grease gun and lube it.

hi sages - a follow up question on my upcoming center bearing job. how do yousuggest i press off the old metal bearing fromthe driveshaft section and press on the new bearing(after i remove theold rubber grommet) . looking for a shortcut to avoid going to the cleaners. thinking of a pipe nipple and hitting itevenly with wood pieces on both sides. thoughts? thanks tons. oldduke

This may be one of the U joints that is freezing up, the only way to know for sure is to flex them in both planes to see if they move freely and not binding. The rear one seems to go first.

I've done the job on a 740 which is about the same. I think the bearing can be had for about $25. from fcp. Not that easy to get on and off if you don't have proper tools, but I do remember seeing a video on youtube on how to remove a center bearing. The guy uses a grinder pretty effectively.
