AWD Rear Wheel Bearing Replacement?

Hello

I found this great discussion on getting the rear axle out:
https://www.matthewsvolvosite.com/forums ... hp?p=66932

This describes most of what one would need to get the rear wheel bearings out on these early AWD cars, but it's actually a discussion about the axles, so it stops short of explaining the procedure for getting the wheel bearings in/out.

VADIS/AllData say the bearings need to be pressed out and pressed in.

Has anyone attempted this? Any luck?

I think the old "freeze the bearing to shrink it" trick might work for getting it in there but I'm feeling a little lost about how to get the old one out.

Any advice would be appreciated.

I would also love to hear any ideas folks might have for determining whether a driveline noise is coming from the wheel bearings or some other part of the rear end driveline (diff, axles, etc). (Also, my car is currently missing its center prop shaft so the rear wheels are only being dragged along for the ride...)

I did figure this out. The bearings NEED to be pressed out with a good press setup. You probably don't have one

I took the bearing carriers off the car (the big steel piece into which the bearings are pressed) and took them to a shop along with the new bearings and snap rings (which are huge BTW).

The shop removed the old snap rings, pressed out the old bearings, pressed the new bearings in, installed the new snap rings. I think it cost about $50.

I then installed the carriers back in the car.

I would have liked to not be doing the work in the freezing cold in the winter but overall the job went pretty well.

I replaced the driveshaft seals on the diff while I was at it, replaced the diff oil, and refurbished all the brake stuff as well (greased the slides, adjusted park brake, etc).

Hi,

I need to replace the rear right wheel bearing on my 98 v70r. I was hoping you could tell me what I need to take off in order to press the bearing out.
My idea so far is;
-Remove wheel etc,
-Compress suspension. Is this to release pressure on bolts? Does it need to compressed to remove just the bearing?
-remove control arm bolts, upper and lower, remove stabilizer bar bolt and abs sensor.
-slide hub off and press out/in bearing

What am I missing or not understanding?
How long does this take? I need to do it an evening. The good news is I should have the use a car shop. I hope they have a press.

Any info will be greatly appreciated.

To be honest I think it's a bit of a stretch to expect to get this done in one evening.

I have revised my original thinking about needing to press the old bearing out - I think you could probably cut it out, which would probably make more sense for the DIYer. I think I still prefer the idea of taking the carrier and bearings to a shop where they can do this part for you - it's just a lot of work and much much faster and easier with a proper press. Also it shouldn't be expensive.

As to the exact step-by-step about which bolts to removed when, I can't remember much of it - it was quite some time ago. I do remember that the suspension needs to be compressed for part of the removal/assembly process.

Also make sure you have all the parts ahead of time - you're not going to be able to just run down to NAPA and get them, and if you don't order online they'll likely be quite expensive.

I also highly recommend attending to some of the peripheral stuff while you're in there as I did - axel seals in the diff, change diff fluid, recondition all your brake stuff, to make sure everything is working right. You've got to take it all apart anyway...
