shaking steering wheel

Hmmm.

I don't think this is due to a brake disc.

Firstly i'd get the wheels balanced again and get your suspension geometry checked on a 4 wheel laser alignment system.

My other concern would be that you only replaced the wishbone on one side. My instinct would be to replace bushes etc in pairs as what you have now is a brand new set on one side and old ones on the other. This will inherently make one side stiffer than the other and may be causing your problem.

I agree with Andrew, it'll not be a warped disc - although they do happen. Nothing in the brakes could cause the 50mph shimmy. 

Most likely cause is the bushes - get the other side done, and get it aligned.  Also, E39s are a bugger for wheel balancing - do you trust the folk that did it?

just a note to remind you Davo, to check that the front hub isnt slightly bent after the kirb. I know of situation where as a result of a kirb incident a slight judder became progressively worse. it was discovered that the disk was warped, not as a result of the kirb but as a result of the brake bads trying to keep the disk straight when infact it was the hub that was slightly out as a result of the kirb. this, i imagine caused the brake pads to wear the disk irregularly thus creating a wobble, at first when braking and eventually without braking. if a new disk and pads are fitted,it may be ok for a while but eventually the wobble will return. so no harm to check this.

hi guys

thanks for all the input the funny thing is i didnt hit the kerb hard

ok i will try simplify it for yous

1.hit kerb steering almost completely gone mainly from left side which i hit

2.went garage got new is it track rod front left(cost me 280euro)

shaking still there

3.got wheels all 4 fully balanced and alligned(85euro).front left wheel buckled

4.got 4 new 16inch turbine alloys second hand(cost 120euro)tyres great nearly new still shaking

5.went nct FAILED on front left wishbone/bush.

6.went garage put whole new wishbone with new bushes  onto carand seen the rubber bush was broken .so new bar and bush for failing front left side(cost 256euro) still shaking.

7.passed nct last week on slip slide test nct till 05/11 now.

8.i didnt get new wheel alligned or balanced yet but vibration greatly reduced at 50 mph and slight vubration of steering wheel above 50 and braking above 60 car steering shakes till it goes below 50mph and no shaking.

in other words if i constantly went below 50 mph i have no problems but above 50 mph i do.thats the annoying part.

i will get new wheels alligned and balanced this sat.but whet annoys me is that the i paid the garage in total over 700 euro and still no joy so far so please HELP ME as i explained the shaking to the mechanic and he looked at brake discs and said there is A LIP ON THEM and that explains the shaking i only hit the kerb mind you at 15mph and the wheels where fully locked but paying another 85 for balancing wheels this sat and possibly new brake discs im looking at over 1000euro or more so please help ha oh yeah i do trust garage

thanks

I paid 25 pound the other day for a hunter 4 wheel alignment

Still need new front tyrs though now!!

This included the front adjustments only though.

If the rears need adjusting, then its another £10 a corner. However 9/10 times its only the front wheels that needs doing as they allign the rear wheel motion with the front wheels, so your only paying for whats required.

On the E39 you set the rear wheels up first and then align the front to the rears.  Not the other way around.

Granted my E39 only needed a front adjustment as the rears were o.k. but I paid full whack.

PS Dan, I've jacked in WYG and I'm now at Network Rail!

I would agree with most of the above regards tracking and changing both arms together.

Can you pin-point the vibration?

Where did you get the wheels?

A colleague of mine had a problem with vibration and changed his tyres everything balanced up ok and vibration was gone. As the tyres began to wear he noticed the vibration coming back turned out it was the alloys. They where fine with good tyres but vibrated like hell when worn.

I would suggest getting the hub assembly checked aswell. I spent over a grand changing wheel bearing, brakes, tyres, tracking only to find it was the hub assembly.
