What the! Whered that noise come from!

[DentonR33]

Guys, just noticed something with my car last night that hasnt happened before... any help would be great on where to take it or what to do.

When rolling there is a thud thud thud noise coming from what feels like the rear end.. feels like a tyre flat spot but i dont think its that cause it just started doing it last night and this morning.. its hard to pin point where its coming from with the exhaust. But i can feel it when rolling. Could it be suspension? diff?

Anyone had anything else similar, i hate when stuff goes wrong with your car, just gets you down

Hmmm,

Wheel bearings? But I think they give off a whirl noise when they go.

Maybe check the universal joint at the drive shaft/diff ?? You know that yoke thing at the diff.

Good luck

does it make the noise when u turn slow?

if so its the mechanical diff u prob have in your car!

i got a mechanical diff in my car 2 and it makes a weird noise sumtimes when cornering slow!

yeah my mate has one of these mechanical diffs, and i know that noise quite well from driving it and sitting in it lots of times but its not that noise

its only when rolling straight, even accelerating

more noticeable when going slower though

Check your tyres. There may be part of the tread hanging loose. If there is no surface cuts check the tyre isn't de-laminating as well.

jack the back of your car up and spin the tyres around to check there isent a piece of metal or sumthing stuck in 1 of your tyres!

Likely a wheel bearing.

Did you lock the brakes that day?

[DentonR33]

i locked the brakes the night before actually to avoid hitting a wabbit.. didnt think i had abs..

where should i take it to get checked?

[Silver-Arrowz]

Jack up the car and rotate each wheel to find a flat spot.

[DentonR33]

So when i find a flat spot if there is one, how can it be fixed? new tyre? or can u balance it out?

if its bad its time for new tyres! :eek:

i locked my front up in my old car so bad that it warped the two front tyres so bad that at over 100 the car would bounce and the steering wheel rattle really bad!:

Well that would probably explain it....

You can get the tyres scrubbed but probably not worth it.
