Drone.............. wheel bearing............

[Upatdawn]

Merc E250 2014 plate

got a drone from the front which gets a bit louder on braking, garage tightened the bearings up a bit but they didnt feel good to me and its still there, heres the rub..


Local merc indie wants £300 to supply/fit/labour/vat one bearing

Merc will supply me a hub c/w bearing for £197 inc vat

I can buy the SKF front bearings for £35 (inner and outer)

(all above for one side)

do i need a 10 tonne press to push the bearings out and in?


(they are taper bearings, its just the cup the race runs in that needs knocking/pressing out)

Done a lot of taper roller wheel bearings on various vehicles & trailers incl my Sprinter.
I've never needed to use a press to remove the bearing race - just a hammer & length of steel.
I've put the new ones in by either press or hammer. I have both options & IME nothing to choose beweeen the two. Cutting a slit in the old one with an angle grinder & 1mm disc means you can use it as a drift & not worry about it getting stuck or damaging the new one.
I have always adjusted taper rollers so with the wheel & tyre fitted I can JUST detect free play when I hold the wheel at 12 & 6 & rock it. Never had an issue with noise, MoT or anything else.

after the O/S was tightened up i could still feel a slight rumble but theres no left/right or top/bottom play

its dur MOT next week then ill see

I got me a plan...

ill buy 1 hub/bearings £197

change what i think is the baddest side, if i need to do the other side ill have a spare hub and can fit a pair of bearings £50


So under £250 instead of £600 (if i graze a few knuckles so what)

i can clean up the pads and discs at no extra cost too...

[Upatdawn]

well.... rear discs off revealed 1 side the parking brake shoes were free and floating as the springs had broken (it passed its MOT like it) , after many new parts i put the spare wheel on the NSF (the newest tyre) and all noise is gone.............

suspected "sawtoothing".........got told i was lucky to get 11,000 miles out of budgets

For future ref' to check bearings..

Jack up car, spin wheel, whilst wheel is spinning feel for vibrations through road spring. Shouldn't be any if bearings OK.

The tyre wear is called castellation - stepped wear. Common on mercs, even more so when run with cheap tyres.
