XC90 Rear Hub Replacement Tutorial

Post by **KeninKenmore** » 01 Apr 2013, 16:54

Here is a tutorial I put together after having to replace the rear hubs on my 2006 XC90... after doing the first one. It was easy, and I didn't see any other tutorial on it... so here's my shot at it. If anyone has the torque ratings, I'll add them in - I don't have any manuals so had to guess

...Hope this helps someone else!

FYI: In between replacing the right and left sides, I adjusted my parking brake... the right side I had to wiggle a bit for it to slide over the parking brake pads due to slight groove in the rotor. If yours has been on longer, you may need to adjust the parking brake a lot looser to get the rotors off & back on...

Great tutorial Ken. I can't thank people like you enough for providing info like this. Makes it easier for experts, shadetree mechanics(like me) and novices alike.

Hi thanks for posting. Did you have any issues with removing the ABS sensor?

Sensors do not have to be touched... it was an amazingly simple repair considering the cost the dealership wants to charge for it. After I did one side, i decided I needed to do a tutorial to show how easy it was to encourage others to tackle themselves...

Great tutorial. I found it very helpful and kept it up while I worked through the replacement on 2006 XC90. Based on my experience the potential impact of rusty parts was not well addressed. The rotor was rusted to the hub and all the tapping with a padded mallet and metal on metal on the center of the rotor was not moving anything. I finally attached a C-clamp to the exposed side of the rotor and rigged a 2-foot steel bar through the C-clamp frame and across the hub which became a fulcrum. Then I could strike the opposite end of the bar hard enough to get significant force in the right direction.

Compared to the hub the rotor was a piece of cake. Hours of tapping and dithering moved nothing. After trying all sorts of lash-ups I broke down and rented a substantial puller. The puller was rated at seven tons and was well taxed before spline rust gave a little. I was a hard pull throughout the length of the spline with probably 20 good "pops" before the job was done.

Though I wire brushed and scraped rust from every spline, reassembly of the greased spline was difficult and I could barely get spline engaged and could not force it into place by hand. Since the center bolt was not long enough to reach the internal threads of the spline shaft, I found a long stud with threads that matched. I engaged the stud in the shaft threads and put a nut on it. I fitted an adjustable wrench under the nut and used the wrench as a lever against the hub body to pull the nut, stud, and spline shaft into place. The lever probably gave a five to one mechanical advantage and the nut was easily adjusted to ratchet the spline forward.

I only go to this details to warn folks that this two hour job can take much longer (especially without access to a puller). I my case it was a long half day.

FYI- I got about 100k miles out of these bearings in a vehicle that very rarely carries any load but has seen lots of moisture (no salt). In this day, this seems to me to be very poor performance.

Great tutorial. Just did the fronts last week and I'm doing the rears today. I got 170000 out of mine and I live in New England where there is a lot of salt and I use it to go on vacation with a full load of people and stuff pulling a trailer from time to time, so I guess it's a crap shoot when it comes to how long they last.
