2000 v70 xc propeller shaft carrier bearing replacement

Is this center support bearing replacable? I can't see how it can be disassembled. It looks like a shrink fit of the knuckle into the driveshaft?

If I can replace the bearing for under $100 it is worth it to get one more winter out of it. The car isn't worth putting a rebuilt driveshaft into.

Depends on skill and tools available. You can grind off swaged in UJs and replace for about $25

How about calling Erie fir a used one?

If you aren’t driving it enough to justify a $100 repair, you can probably Uber for less

Makes quite the noise doesn't it?

Same thing happened to my wife's and I just took the shaft off and forgot about it. The car drives just fine without the prop shaft.

There is a spline and the two parts are slid together. You have to heat the area with a propane torch or oxy-acetylene torch and then it will come apart. Use green bearing mount LocTite to put it together after driving off the center support bearing and installing the new assembly. driveshaftparts.com has them.

Thanks Jimmy! I'll try heating it before beating it. I didn't see any indication it was splined so was afraid it was a press fit.

I would suggest that you scribe marks on the shaft so that it can be reassembled in the same position that it was taken apart. I was unaware that it was a splined so I have never seen them but if it isn't keyed in some way you will want to get it back as originally built so as to maintain the balance.

Yes! Absolutely keep the original orientation of the two parts. Look and make sure there is no set screw also. I don't recall seeing the set screw past early 90s RWD shafts.

I am in the same boat as the original author here. My V70 XC is a 1999.

I see that the three wisemen from the East participated in this discussion, abscate, Jimmy 57, and Ozark Lee….

Here is my shaft after cutting the old bearing off. Not crazy about how much damage I did to the shaft.

I put a MAP/Pro torch to it and then beat on the back of the U-joint yoke without success. How much heat should I use, where should I use it, and where should I apply force to separate the two halves?

I do know to make aligning marks before I pull the two halves apart. I have access to a TIG welder and a competent operator. Should I repair the cut I made in the shaft cutting the old bearing off before putting the new on on?

Thanks, take care, and stay safe,

I think I would pass on trying to patch that , it’s pretty small in the scheme of things. Put it back together and see if you have any vibration

As I mentioned in the other thread, there is a chassis break in the part numbers for the support plate,

...but they don't show it on the dealer page. I couldn't find one used for my '98 V70R, but Robert Spinner did find one later, you might check with him.

Text usually works better than email, or call him.

I don't know of any mere Mortals who have rebuilt a shaft; given how rusty your u-joints are, my guess is getting it apart any further will be brutal.
As abscate suggested on the ancient thread, used might be a better option, but shipping wold be a challenge.
