Thread: Fitted new wheel bearings, 4 weeks & ~1k km later this....

Fitted new front hubs / bearings a month ago, genuine Timkin ones. My15 D4 with 157k km, noisy ones were originals. Did both as couldn't distinguish which one was noisy.

Whilst changing the fuel filter earlier I noticed an explosion of grease (dark green / black) all over the inside of the drivers side wheel, caliper etc. Passener side has only about 10% of the same mess.

Bearings aren't noisy and if I hadn't been under there for the fuel filter I'd have not noticed it.

Best guess is it seems to be coming from the bottom of the boot / gaiter - but I can't see any splits and not sure what it is.

Any ideas / suggestions?



Thanks.

I had the same issue, having a look at your last pic it shows the large clamp/band not running true with the hub.

there is a locating groove on the cv hub and a ridge inside the cv boot that is about 1 cm inside the edge of the boot i.e. you push the large end of the boot past that groove so then once the band is clamped tight the inboard edge of the metal band (or zip tie as some use) is locking the cv boot ridge into the cv joint groove.

The giveaway is the splatter pattern ( CSI JohnP38 at work) being deep inside the wheel.

So just take off the band, pull boot back to see the locating groove and feel inside the cv boot for the ridge and you'll get what I mean, mine was slipped askew like yours and same result, it is very hard to hold the boot located properly in the groove while tightening the band, I actually ended up using 2 x 3mm wide zip ties and a few days later when I replaced the inner tie rod on same side and had procured a metal band I decided to leave well enough alone as it was sitting spot on and no more slime over the wheel.
