FJ Cruisers of Northern California

Rear Diff or Hubs?

Ok after my 1500+ road trip I got some pretty interesting noises coming from the back end of the FJ and could use a hand getting it figured out before the Grass Valley Run

After jacking up the truck and poking around
I think it maybe the E-brake shoes on the passenger side but unsure as how to get to them

Jack up the rear, pull the wheel, then pull the caliper, then pull the rotor and you'll see the ebrake shoes. The ebrake shoes ride in the backside of the rotor. The shoes are really simple to swap if your dealer has them in stock.

Thanks Sol, just needed a pep talk, if it's the bearings then what? pull the hub? and how easy is that to swap? Thanks again, once I've done a job it's cool just haven't done this

If it's the bearings then you'll have to pull the axle shaft (not hard) and have the old bearings pressed off and a new bearing pressed on. If you look at my SACDFJC Phase II build thread on the blue room you should find a couple of pictures where I pulled the axle shaft and pressed the bearings off. Once you get the rotor off you need to remove the speed sensor wire, then there are 4 bolts that hold the axle shaft bearing retainer, backing plates, ebrake setup, etc. to the axle housing. Once those 4 bolts are removed the axle shaft, backing plate and other parts will slide out of the housing as an assembled unit. Once the axle shaft and bearing assembly are out you will need to have the bearing pressed off the shaft and a new bearing and retainer ring pressed on the shaft. The bearings are fairly expensive as the speed sensor ring is built into them. Most dealers should have them in stock or can get them in a day or two.

Just thinking out loud, have you checked with your dealer to see if the wheel bearings would be covered under the drive train warranty? I know you have a lot of miles, but might be worth the call to the dealer before digging into the bearings. If not, changing them isn't terribly difficult, but will probably take a little time.

how do you get the rotor off (large hammer?) or am I missing something, when I turn the wheel (off the ground) while the E-brake is pulled I can hear the spring making noise and lots of rubbing

The hub assembly comes with the bearing and pressed already. The hub assembly is attached to the differential with 4-bolts.

Assuming that you already have the brake caliper off. The only thing that holds the rotor on is the ebrake. Make sure the ebrake is released, then use a rubber mallet and whack the rotor a couple of times to break it free. It could also be that your ebrake assembly has come apart and it holding the rotor on. I'll PM you my phone number, give me a call when you get a chance.
