Diff Bushes Done, Now Clunk/creak Noise And Burning Smell

[Jezzza404]

Hey guys,

I just got my rear bushes replaced for my diff

Now when I apply brake pressure (and hold from 70 to 20 kph), there is a creaking noise and when I let go there is a clunk noise. Even going slow speeds the creak noise is loud, and the clunk is still there

If I brake very slowly and steadily down to 0, and slowly release my foot, there is no clunk..

It only sounds like it is coming from the rear right drivers side

It also has a burning smell like clutch/handbrake on all the time

Sounds like my rear caliper is loose?

Ive had a look under the car, and it appears the rear centre has been changed to a polyurethane bush, but cant tell what the side ones are

I dont suspect its the bushings

Anyone know?

I have told the shop, they said to bring it in. They said they will look at it

The noise wasnt there before, just hope they dont try to shaft me!

Poly bushes generally introduce more noise. Clunking in usually one of the symptoms. You should ask them what bushes they fitted (I.e. what brand and model) as some transmit more noise than others.

Thanks for reply

I read the how to change diff bushes, doesnt appear you need to fiddle with brake calipers at all

It only happens when I brake though, and it did start to have a burning smell

So I suspect its more than just bushes wearing in?

edit: Ill also add, that my gearbox and tailshaft just got done too, its about 50kms old!

The noise was definately not there before my diff bushes got done

Yep, like I said, poly diff bushes tend to transmit more NVH than the factory rubber bushes. If you can find out which bushes were fitted we'll be able to tell you a bit more.
