2007 GS350 AWD Rear Bearing Replacement - notes
Hello,
Used to have SC300 and SC400, my friend asked me if could do a rear wheel bearing replacement on his GS350. Huge thanks to rkw77080 for this DIY great job on details and pictures.
However GS350 had different rear brakes set up so i couldn't use second hole to pry dust deflector.
Below is my experience and the way i found easier way to do rear hubs:
BE PREPARED TO BUY NEW SPEED SENSORS - aluminum rust and holds brittle plastic sensor really good, extraction can be difficult because hole narrows towards the axle. I broke one sensor, then a drill bit, then a screw, then lost my mind but used a smaller drill bit drilled 4 holes around the broken screw and got all the pieces.
1. Dust deflector does not actually obstruct access to bolts - it is axle only
2. Raise the hub to operating level so axle is in line and straight on both ends - push the axle in with pulley puller (i used 5 ton from autozone). it will give you enough room for 10mm hex socket 3/8 extension 3" or 5" for far rear lower bolt
3. Dust deflector will most likely rust to the hub so removing may be tricky. one hub spit, but beating the living s..t out of it in strategic places with shimmies will loosen it up
4. Clean dust deflector from rust and alight speed sensor hole
5. Follow the about above DIY (post #10)
In other words:
Push axle back to gain access to 4 bolts holding the bearing (no need to remove dust deflector) - that's the only difference between LS and GS bearing removal
P.S. If this info has been covered - i'm sorry, i couldn't find it so i thought i'd share my experience. Overall it took me about 8 hours (probably less, because i did it in two days)
P.P.S I used too many tools, you don't need all that. All you really need for tools is 1/2" for axles nut with 32mm 12 point socket(Sears) and 3/8" for 10mm hex, screw driver to align dust deflector. Couple more tools for taking off the wheel and brake caliper: 21mm wheel nuts & 17mm caliper bolts
P.P.P.S if i forgot something please let me know, i was also doing brakes, ballasts, bulbs, sensors and some other little things on this car so some info could be mixed or forgotten

Just what I'm about to do! I need to clean my abs encoder ring in the bearing. What torque specs did u use for the bolts and nuts? Any other things to be aware of? Do I really need a second jack to bring the axle level? Also can I get away with the gear puller?

b) I followed other DIY from rkw77080, he had all torques in there
c)just be careful, watch for caliper lines, abs wires
d) I used second jack to straighten the axle so when it pops out it doesn't rip any boots or damage anything
e) you can use whatever is easier but "Claw" was free rental from autozone

So those tools you show up there is all you need? No press or anything like that? I urgently need to tackle this job but have been putting it off because i'm a little worried. I've never replaced a wheel hub/bearing. I've done shocks, brakes/rotors, timing belt/water pump on my car, just never done this. Anyone else ever have any issues?
Only part needed is in link below, right?

hey I just ordered a new bearing for my right rear wheel and got it for $54 shipped from rock auto.
I'm a lil concerned tho cuz everyone else is quoting at least $150.
can someone who knows about this stuff please tell me if this is an OK bearing to install?
thanks so much.

I've got a constant humming noise (increasing on speed) from the back on my '05 3rd gen GS300 RWD as well, most noticable on recently paved tarmac, at 50mph and higher.
I changed the wheels already, changed the diff-oil (almost no particles on the magnet-plug), and rebalaced the wheels but no effect. I sometimes wonder myself getting picky on any noises, as the car is so quite afterall. I bought a SKF rear bearing assembly. From the driversseat it seems to be the right rear bearing, but hard to position/allocated as the noise reverbs in the cabin.
Like Scotty Kilmer I haven't experienced any play on the fiddling tricks on the wheel. Local Lexus Dealer was busy moving to another location. Local Toyota dealership made it quite difficult accepting the job as they incisted me getting to the dealership near my work 50miles away.

Does the noise sound like helicopter landing?
My GS2007 AWD has that noise. Toyota dealer said it's the front wheel bearing.
Brought the car to a local shop, the mechanic didn't think it's the wheel bearing.
He told me my car tires (Michelin Pilot A/S 4) are scalloped. That's probably why the tires make that humbling noise.
I had him replaced the front bearings anyway since the car made a grinding noise when I steered the car left/right and drove forward.
The grinding noise went away but the humbling noise is still there. I had the tires re-balanced and rotated. The noise is a bit better now.
So check your tires.

That is probably a bad wheel bearing.

Today I started to replace the rear RH wheelbearing. It was a PITA after all with a stuck ABS sensor and had to remove the whole bearing assembly from the suspension. The bearing was rotted into the assembly. Eventually I needed to drillout the ABS sensor. Need to finish the job tomorrow to reassemble all things. It has been said in this DIY but it’s a job where you can fall from issue to issue. I learned a lot today but I may consider to leave it for the dealer next time.

Does someone have the torque specs of the suspension part and the hub-nut etc? I found the hub-nut for instance, torqued at the 2004 LS430 @ 214ft-lb and on a 2006 IS250 it's 76ft-lb. I didn't found any torque specifications for the 3rd gen GS300 in specific.
