Evening.

 

Looking for some folks input on this. Theres been a nasty rumbly noise from the front for a while.i put it down to tyres as they were quite old and all diffrent budget brands.Popped on 4 decent new tyres and the rumbly loud road noise at 50mph has gone. However now im left with what can only be described as an old washing machine spinning up, Its unnoticeable below 30mph then as it reaches toward 40 it sounds kinda deep and rumbly spinning up to about 55-60mph where the sound is almost like a high pitched gear whine. on deceleration the noise sounds almost like a car after a dyno run and the thing is spinning down. I thought gearbox but im thinking not now as the sound is changing with steering,worse on a right hander quieter on a left, indicating a possible left side bearing. Prob is both front bearings were done only 3months ago. everything seems fine down there only thing is a small tracking of grease on inside of wheel arch liner around area of cv, i closely inspected the boot and its in good nick and no splits whatsoever as are the other ones in and out.pinhole possibly?  only other issue were when i done the bearings i reused the old hubs and the left one ended up with a small nick when i was cutting off the inner race but were talking small here ie less than 1mm deep and 10mm long.

Cant think of anything else as this is a really unusual noise that changes as it moves and not ur typical bearing drone thing.

Does anybody have any ideas about where my problem is or could detail the various symptoms of diff bearing failure.

 

Thanks.

 

 

Hi. Is it a gearbox sound. For instance. My car has a low pitch whine sound in 4th gear at 40mph gets really high until i change into 5th at 50 to 60mph

Mine is bearing problem gear box.im having recon box soon.

Is there any nocking sounds on yours?

no thats whats kind of steering me away from gearbox as its the same in all gears clutch in or out and even in neutral coasting.no knocking just an odd whirring and then a whine higher up in speed.

Goosed Differential.

how would i go about confirming a wonky diff without taking the box apart? i still have 2 fresh front bearings in shed as spares it might be worth trying them just incase
