Front wheel bearing adjustment?

[Koenigturbo]

Is the front wheel bearing adjustable? Is has some play, but not bad. It dosen't make any noise's ThaT I can hear when I'm turning corners. I was talking to a mechanic and he said the nut coild be loose.
How is it that the nut can come loose?? Isn't there a cotter pin holding it from moving??

there is no cotterpin holding the front wheel bearings, they are pressed in, not unless he is saying the knuckle is loose and one of the nut is missing a cotterpin maybe? but i don't remember the front knuckle even having a cotter pins, if there is play with your wheel bearing i would definately get that taken care of i wouldn't wait for it, and also double check your ball joints to

What are you talking about? Yes they are pressed in, but if there was no nut holding it, the cars weight in corners, etc would so pop it out, lol. That being said, there is no cotter pin, I believe it is a stake nut holding it, if it wasn't staked properly, it could come loose.

That being said, usually you'll start hearing something before you feel something from a bearing, are you sure the play is from the bearing.

Where is the play coming from? Up/down, left/right or all over? If the nut was loose I would think it would move in and out only. If the bearing was loose enough to show play you would definitely hear some noise.

Don't see how the nut could be "loose" at all the Tq spec is "FT"
("fucking tight" aka 147 ft/lbs and as Jeff has pointed out the nut is staked so can't back off)

The mechanic guessed (wrongly) that our system is like old Ford sedans with tapered roller bearings. Those pretty much get adjusted by hand until they feel right, then a cotter pin keeps the nut from moving. The nut isn't tight enough to keep itself from moving. If there's play, you can sometimes get rid of it without replacing the bearings.

Since Toyota didn't do it that way, the mechanic was wrong.

The MK2 and other Toyotas do have it set up like that. Though there are measurements for it and not just until they "feel right" though. You torque it and then loosen it off and tighten it until you get the right resistance.

There is no cotter pin......

Time to either learn to do it yourself or find a mechanic that knows Toyota's.

As much as people love loud exhaust on their Supra's, I wouldn't be surprised if you couldn't hear the bearing roar. That said...

There is a snap ring in the back of the knuckle that holds the bearing in. You have to remove the rear cover, remove the stake nut, press out the hub, remove the snap ring, flip over the knuckle, and press the bearing out the back. Replace the seal while you're in there, and assemble in reverse order.

Thanks for the reply: the bearing moves up and down and side to side about an eight inch, as far as hearing some thing, I didn't hear it when I had my queit stock exhaust, I sure the hell isn't gonna hear it when I have my after market 3' inch exhaust (Not being an ass I'm just expressing myself)

Thnaks!!!

O.K. Ij I gonna agree, I looked in the manual and it is staked in and I don't believed it backed out, especialy at 147, L.B.S of torque so, I wouuld say the bearing is "N.G."

Doing it myself??? I don't think thats a job for the back yard mechanic that doesn't have the right tools or press, or puller, "IJ" I wish I had all that stuff to do it.

You could do the bulk of the work then take the Hub to a shop have them press the new bearings in then YOU tighten it up and stake it so you know it's done right

This approach will save you a heapOcash and you will have confidence that it was done right.
(Man I'd HATE to drive that car at speed thinking all was right)
