well crap....rear wheel bearing

[dixie_boysles]

Wel it seems that my T4R with 145K miles is gonna need a rear passenger wheel bearing. Been hearing a roaring that has gotten progressively worse thinking it might just be tires wearing (BFGs do get quite loud). After getting a flat tire from a sharp rock in the road and having it fixed decided to check the bearings.

When I had it jacked up in the air, I just rotated the tire and you could hear the bearing rattle a bit or something. Did not turn too smooth.

Odd at 145K miles but these are mechanically parts and not everything is always perfect.

Best price I've found is $105 for a Timken on Rock Auto and I have family that mechanics, so maybe it won't be too bad.

I just replaced the rear wheel bearings on my 4runner in December. You will have to get or build the Toyota special tool to press the bearing off the axle shaft and press the new bearing on. I ended up taking the shafts to Toyota because I couldn't find anybody that had that tool and I didn't have time to build one. Other than that, it was a fairly straight forward job. As for parts, wheel bearing for each side (only driver side was actually bad though), inner and outer seals, new bearing retainers (this is the part the inner seal rides on to seal), and new c-clips. I also had new studs pressed into the new bearings and new nuts to go with them. The hardest part was re-installing the parking brake shoe retainers.

Hey thanks for the heads up!

I'm getting a Timken bearing, where is best place to get the rest of the parts you speak of

Pretty much everything but the bearings I bought from toyota. You may be able to find the seals aftermarket but everything else will probably be dealer only. Not only that but the two closest dealers still had to order most of the parts in. It was kind of expensive but I wanted to make sure I had everything I needed and to do it right. The (sort of) comforting news was that they had only had to order these parts in for one other 4runner with way higher miles. They (the dealer) were surprised the rear bearings had failed so soon.

Oh and another thing, if you take just the shafts to get the bearings pressed at the dealer, take your vin#, license plate#, etc, because apparently the service computer has no way of entering just piece work. A ticket can only be entered for a whole vehicle. It was kind of funny when the cashier called and said my 4runner was washed and ready to go, even though just the shafts were there.

I don't see an inner and outer seal. Just an o-ring, washer, retainer, c-clip, retainer, and seal.

So I ordered the retainer, o-ring, and c-clip and of course the bearing. Didn't see a need to replace washer.

Sorry, I should've been more clear. The outer seal is just an o-ring. The inner seals look to be part#s 42311V and 42312C according to the pic. I guess it's a toss up wether or not to replace them. I didn't replace the washers either.

Ok great. I was able to obtain all my parts for $161. I bought a Koyo bearing from Napa along with the seal for $136. I had to get retainer, o-ring, and c-clip from Toyota for $25. So all in all I am pretty happy with price considering Toyota wants about $380 for the bearing alone and it's a Koyo from my understanding.

i'm going through the same problem...i bought my Hub for $60 and thats with overnight shipping from rockauto and i had to order the retainer thats right after the hub or whatever...just waiting on the retainer, definitely the hardest thing was the ebrake shoes so far

Did you press bearing off or hammer it off or what?

 

[gm350reratliff]

I had the old bearings pressed off and the new ones pressed on. I have a press but not the special tool. Now that I have the old bearings apart, I can make my own Toyota bearing tools. Just gotta find the time.

So even with a pressvyou still have to have a special tool? What's this special tool you speak of

sorry...but i had to have the retainer sleeve cut off and then hub can be pressed off...to install the new parts, you have to have the retainer sleeve heated to 700degrees to be pressed on then with the hub

One more piece of advice. On the rear caliper brake line bracket, drill out the two spot welds to separate the bracket from the backing plate. This way you won't have to disconnect the brake line then bleed it. To re-install, use two 1/4" stainless steel bolts and self locking nuts with just a touch of anti-seize. I can't remember if I used 1/2" long bolts or 3/4" bolts though. When your drilling, put a piece of metal like a putty scaper or something in front of the brake line so when the drill bit goes through it doesn't damage the brake line.

I cleaned up the rough edges on the bracket and backing plate and used a little primer (I was out of black paint) to protect against rust.
