Rear bearings

[Gary820]

Just a quick one for the wise, need to adjust a rear wheel bearing which doesn't seem too much of a big job. Will make a tool or pop next door to Toyota and borrow it, going to order a bearing kit just incase!

Obviously the shaft needs to come out, are the seals generally fine to just slide the shaft back in or is a new seal everytime? I'd guess same as the front, genuine all the way is best?
Must admit didn't realise they're taper roller bearings at the rear, didn't look that close when did the brakes lol.

Genuine seal is best. It's not an automatic replacement but then again they don't cost much. If you can feel play with the shaft in then there's probably more play than you think once you get the shaft out. The stiffness of the shaft can mask quite a lot of play. They are the same bearings as the front but the hub seal is different. They may just want nipping up and not need replacing. Nice easy job with an impact screw driver for the screw in the locking ring.

Did one yesterday Gary. Child\s play. I'd like to see the Toyota SST. I have never used one nor really needed one. I have spare oils seals in stock but didn't need one. If no oil runs out when you crack the half shaft then you inner seal is probably OK. My wheel had a heck of a wobble in the hub. Bearing was pretty much on the point of collapse I think. I could pull the inner race out of the centre section!

Cheers Jon, I'm gonna get some bearings and seals just incase. It's only a small amount of play on one side, best to do it before a battering around Wales lol. No noise or roughness when spin it so hopefully a quick job, not like truck done big miles! When I stripped the front end I don't think it had been touched!!
Thanks for the tip ref the screws. I've text my mate at Toyota who's gonna get me the tool to borrow and order me some seals.

i used mixture of FSM and this http://forum.ih8mud.com/threads/how-to-rear-axle-rebuild.732072/ when rebuilding the rear .

Pretty straight forward. Might be worth getting a few spare locking ring screws, mine were well mashed by time got them off.

The innner bearing grease seal on the rear is slightly different than the front as has a rubber lip. Could probably use one same as front but being OCD I replaced with original type.

Need to also position the lock screws, line up the lock ring index marks to the spindle index marks:

The red arrows point to the 4 index notches on the end of the spindle. They are located on the diagonals, at clock positions 1:30, 4:30, 7:30, and 10:30.
The blue arrows point to the 3 index marks on the lock ring.
You line up a lock ring index to a spindle index. Use whichever pair is closest to each other after torquing the lock ring. A new pair is lined up at every 30 degrees of rotation. Dave.

Had your monies worth then!!
Too used to Isuzu ones where the bearings are on the half shaft and go in as one piece. Can change a rear shaft on those in about half an hour lol.
I'll pay more attention from now on!
Next weekend job at work on the ramp.

Two 8 mm threaded holes in the shaft end flange Gary. Very handy for jacking the shaft out of the axle. Same cones nuts to deal with as on the front axle.

 

[Gary820]

Good link. Looks straight forward enough.

Didn't have too much of an issue with the cones upfront so hopefully they'll be ok. I doubt anyone has been in there before either.

 

[Gary820]

Got some bearings on order and ordered some seals from Toyota too. Not expensive at all. Have permission to use ramp on Friday to do it too.

I have the SST if anyone would like to borrow it....

 

[Chris]

I'd like to SEE it Justin. can't really figure out why you'd need a special tool to torque the nut then move it to the nearest locking hole. Not sure why they didn't just replicate the front system on the rear really. It's lots of special bits that don't so anything really special.

 

[Justin_Elliott]

Ta da...

 

[Chris]

Shaazaaam! Oh, bit disappointing ha ha.

Wouldn't a 54 mm nut have been easier? Wonder if the threads are the same. 2 nuts and a locker would be easier. Not hard to make one of those actually. is it a genuine Toyota thing Justin?

 

[Justin_Elliott]

It is, totally OOT in my opinion, although, not tackled my rear bearings yet (but this came with the truck). If it made a difference I'm sure it would be easily reproducible!

 

[Gary820]

Well glad I checked that! Grease all washed out with diff oil. Hub seals did a good job keeping the oil in!!! Checked the other side which was fine but gave it a strip and chucked some new seals in. Cones gave me hard time. Looking at it I don't think it's been apart before. Fitted new studs, cones and nuts while in there.

 

[Chris]

Would you Adam and Eve it
Just got back to truck after a day deer stalking near Stirling to find a puddle of oil in the wheel. Yep rear wheel. Did 300 miles last night to get here must have decided to throw in the towel as I parked up. Good job I bought a pair recently
Another job to go on the list.
Ahh well at least I bagged something. Might as well whack new bearings in at the same time once I have made the special tool

 

[Gary820]

Glad I'd ordered stuff for both sides, didn't need drivers side doing really but it's done now. Even with the half shaft out there was no play. Passenger side though

Even with a full history and loads of dealer stamps I'd say for certain all the bearings had never been touched. Fronts were same when had those apart. Not a bad thing imo as not dealing with poor repairs.
