Rumbling from NS, new bearing and driveshaft fitted
 

Long time no see friends,
I did some work on the old girl recently, changed the front hubs and wheel bearings to brand new stuff from good old DMGRS (hence I'm pretty sure its not the wheel bearing)

On the first journey out after the work on the motorway a rumbling very similar to a wheel bearing appeared, I jacked the car up on the offending side, tyre off and had a listen with it spinning, definitely something on the passenger side between wheel and engine, couldnt pin point it anymore than that.

To imagine the sound, imagine rolling a brake disc along a concrete driveway (I've tested with the calliper off and the noise is still there)

As it has a new wheel bearing I've assumed it was the driveshaft and just replaced that this morning but the noise is still there.

To me its either the gearbox or a brand new wheel bearing is failing already?!

Any tips would be hugely appreciated
kindest regards and TIA

Incorrect fitting technique?, poor quality parts?, to be fair it could be either or indeed none of these things, but it is important to not discount items which have been recently replaced as not defective ;)

Start by removing the driveshaft from the hub, backing off the caliper, then spinning the wheel, this should at least exclude the gearbox as a possibility ;)

Best of luck

Brian :D

I shall have to pull it all apart again and try something!¬ unfortunately its the kind of noise you dont hear until about 20mph and up so spinning the wheel by hand is a tricky test :D

have you looked at the intermediate drive support bearing ? ;)


mine was like a dogs thngy in a bucket :o:D:D..

dont say that! I swapped the gearbox out a while back and have no wish to repeat! haha
Ill have another look and keep my fingers crossed its ok, going to try a cheap wheel bearing i think and see the results, it does seem a remarkable coincidence it was after the bearings were replaced

Rumbling noise after reaching 25mph
 

Did you have any luck identifying the source of the rumbling? I have the same problem, new SKF bearing fitted front n/s rumbling started which was n't there before. Grateful for any clues.
