Front suspension.

Recommended Posts

Apologies everyone another old topic so....

 

My car has done 105 000 miles I was getting a bit of vibration on moderate braking and overall a feeling of coming and going shimmy  vibration through the car on and off at various speeds and just some feelings of the front wheels being unbalanced felt through pedals and seat of pants.

 

The tyres are new and decent spec, wheels have been balanced and 4 wheel aligned, but nil improvement.

 

Examination by mechanic revealed play in one track rod end and slight warp in front discs so replaced, no does not shake on braking but overall drive still does not feel right/nice.

 

I raised the possibility of the lower control arms but mechanic was sure that these were okay as was all other ball joints bushings etc.

 

He does not seem to think remaining shimmy vibration is out of the ordinary but does not feel right to me! any ideas anyone or anyone recommend specialist for these cars in North West he is a good mechanic but says he has never had to replace control arms on e60 so wondered if he was missing something?

 

Thanks

At 105,000 miles your E60 should be well into its second set of arms.

 

They last about 60-70k depending on engine size (weight on them) and how it's driven. So he's clearly not seen many E60s then.

 

Its the control arm that fails first, it's the rear most arm that goes upwards into the steering knuckle. Classic sign of it going is shimmy under braking and hearing the odd clonk.

 

Here is how I replaced my control arm and tension arm.

Mine's an E39 3.0d on 102k miles so may or may not be relevant.

Symptoms: a very slight shimmy at 60-70 and a 'squirm' of the car if ever I went over a join in the tarmac, or raised white lines.

Also, what I didn't realise until I had it fixed, was that it was pulling to the left, and I was subconsciously compensating for it by steering slightly to the right.

Yesterday, I had the big control arm bushes replaced and everything seems good, although I've only done 6 or so miles in it.

 

#5, here

The bushes were genuine from BMW (£70) and labour was about twice that, from Ashcroft Autocentre in Penketh, if that's close to you. (For the record, he diagnosed it as the front bushes - I thought it was the rear - and, also, when I took it in for the initial assessment, I asked him to trace a fuel leak from one of the lines near the tank. It turned out to be a split in the little bit of flexi-pipe just in front of the nearside rear wheel - he replaced it for free. He's BMW-trained, too, and one of the techs there runs an E39.)

You should have your tracking done iirc

Thanks for advice/pointers car at the moment has improved for having track rod end and discs done but still feels a little 

unsettled at times and just not as smooth and taut as I would like.

I have read many posts on this topic and plan to use lemforder parts as a matter of course, the suggested garage by Grapefruit is local enough to me consider as they sound as they have a good knowledge of BMW set up as a matter of interest my car also pulls slightly to the left as well a 4 wheel alignment did not solve this but they also could not detect any faults with front suspension.

 

Thanks

A decent garage who does a full four wheel alignment won't do it if there is a fault in one of your balljoints or bushes (as it won't hold the alignment that they set). Although they won't check the top mounts.

 

Assuming the suspension arms are ok and your discs are ok, other sources of a shimmy under braking can be sticking calipers. If it's felt under normal driving, look at your tyres and rims as the source of the problem.
