1990 740GL with AW-70L and (I think) 4.10 rear end

A few weeks ago, I told someone I had an easy time changing my center driveshaft bearing. Apparently I had an exceptionally easy time with the last one because the current one is a bear!

I stopped myself from damaging the shaft (cough cough much) and am going to take it to a driveline shop to fix it right. I'm going to spring for new u-joints too because at 223k, these appear to be original and have the shaft balanced. Once that's done, I might have them check the differential condition.

Hopefully my new plate and registration stickers will be here by then....

Then it needs front struts, sunroof seal, un-messing up the fuel filter plumbing, and replacing the blower motor and I will feel god enough driving it to put a for sale sign on the Honda I have been driving for 5 years. When the Honda is gone, I will get cracking on my real project - the 89 745 that I rebuilt a 1994 "squirter" L-block b230ft for.

My big questions

1) Do I need to take the flanges in with the shaft to be balanced? I think I did last time.

2) What what the idea with these flange bolts? It's basically impossible to remove them without pounding the u-joints out first. The transmission output flange's conical portion on the side with the lock nuts makes it impossible to turn any wrench put on them. I think I replaced mine with internal-hex-head bolts last time I had to do this so that they can be removed without removing/destroying the u-joints.

2b) What size are the flange bolts? M8?




The following is just so that this number comes up somewhere on the internet... lol. I literally could not find any search results for this number at all.

Just an FYI, the bearing carrier I have is marked SPICER 211425 - 1X CR 2 and it is not anything listed anywhere on Spicer's (very poor) website. That particular carrier is different from the replacements, but not functionally. It has a roughly 5" long 4-5" diameter steel sleeve (think soup/bean can size) that I guess is a water/mud shield for the splined slip potion of the shaft as well as a metal dust/rock shield that's integrated into the front (as installed). It would be nice to find one like this, but I couldn't find hide nor hair of it existing much less a matching replacement.


This carrier holds the 60072rsj bearing type that is 35mm ID and 62mm OD. It goes both on the smallest 1.75" shafts and some later shafts with the 8" distance between bearing and center u-joint.

Pulling from the IPD website, the cross-reference numbers are 1209820, 42753010500, 42753010803, 5141209820, 77430030 - https://www.ipdusa.com/products/21207/Drive-Shaft-Center-Support-700-900-small-for-Volvo-Aftermarket-VR167-1209820-246673 and https://www.ipdusa.com/products/5853/Driveline-Driveshaft-Center-Support-Carrier-Mount-Bearing-Kit-for-Volvo-Aftermarket-4K9820-106741
