Vibration under braking only

[E39 Ian]

I have a heavy vibration when I slam on the brakes, any ideas on parts to replace?

either you have a warped disc or it can also be a shimmy caused by worn control arm bushes

I had the braking shudder and changing the LCABs sorted that. What's your mileage Ian?

I had the same vibration on The POFS in the beginning, and then had the lower control arm bushes changed. problem solved.

I was on about 150K KM's on my E39 when my LCAB needed replacing ... similar issue with vibration under braking. However, I also picked up vibration under acceleration too ...

Acceleration is super smooth, THANKFULLY

if acceleration is super smooth, then its definitely lower control arm bushes ...
no too difficult to replace if you have a press. I just removed my control arms, poped down to bmw and had them press in new ones, and then I just stuck em back in the car. and voila.

mine wasted at around 190K also.

I bought the complete pressed units. Still have the old ones if they are worth something...?

 

[E39 Ian]

cost of new bushes?

Where is best to buy them in Cape Town?

Is there a real difference between OEM and other suppliers in terms of quality?

Polyparts in brakenfell - I paid R136ea for poly urethane ones.

Great. thanks!!!!!!!!!!!!!!!!!!!!!! :clap::clap:

I'll give it a try and report back

 

[clutchplate]

eish, ok. hmm, I paid 800 bucks for original BMW ones.. really don't like using aftermarket stuff. unless for a race application.
but poly urethane bushes should be good bro.

 

[Hellas]

Can't go wrong with the poly ones. :thumbsup: And there is no replacing them ever again too!

Thanks!!!!
