Bearing ?

Maduggo · October 24, 2012

Hiya folks

Got what is a bit of a poser question so comments welcome.

I have noticed a grumbling type noise whilst driving along, it seems to be coming from the drivers front wheel, it also speeds up and slows down with the driving speeds.

It is not always there either.

At first i thought instantly... wheel bearing.

Alas not, the car was checked by a local garage and they found no issue of concern, even stated it was the tyre tread pattern causing it.

To test this i swapped the entire wheel with one of the rears and travelled some roads i normally use, the noise was from the same area of the front.

With the front wheel off i spun the disc to listen and feel for issues, couldn't tell anything untoward.

The car has just passed it's mot with no advisories, i even asked the tester to scrutinise the bearing, he said no problem found.

I am now befuddled as to what it may be.

Any ideas ??????

P.S. what is the part number for a Ls 430 front wheel bearing, and appox cost and are they just from lexus?

sounds the same a my problem but mine is n/s/f. was looking for a better bearing EG. SKF , Tiger, FAG, NKE, NGK these are industrial quality bearings which i use a lot in my job and are cheaper to me .I need The actual bearing size though. If i find it I will Let you Know and the Price. This is normallt stamped on the bearing outer race or the seal.

On the ls430 you cant just buy the bearing, you have to buy the whole hub. I remember it being just over £300ish

Is it a non removable bearing then? If its not then there must be a bearing that can be fitted in there. Surely you just need the correct size?

A tip to remove bearings if you cant push them out with a hydraulic press if you dont have access is to break out the inner race and run a weld around the inside of the outer race. the bearing will then just fall out of the recess then a new one can be pressed in
