Hot Lips Posts: 3,302 Group: Members Member #2,380 Joined: March 6, 2008	I'd say half-shaft joint has wear or shaft is slightly twisted or bent! Circular reflections would point to propshaft! Edited by Stempies, Sun Jun 21, 2009 7:33 pm.

Sales Rep Posts: 1,815 Group: Members Member #1,387 Joined: June 9, 2007	if its been there the whole time you have owned the car then its always difficult. A couple of thoughts would be: 1) Wheel bearing - grumbly when straight yet under a turn it loads up and quietens down. 2) propshaft bearing - the gearbox and shaft is quite a mass, especially during cornering 3)Propshaft alignment/imbalance - the propshaft is a balance critical component and needs to be re-aligned correctly if disturbed. 4)brake pads, these can float around in the caliper and cause odd noises from time to time.

Posts: 5,048 Group: Members Member #456 Joined: August 14, 2006	hmm.. are these all things i can check ? or will i just have to bite the bullet and buy new parts and replace to test ?? i dont mind throwing a few quid at it but obviously if possible i want to keep any unnecessary changes to a minimum

Because of the way the suspension works on a 190 it always sounds like the diff until you take a corner. They have to be pressed out by the way! Edited by Big Ben, Sun Jun 21, 2009 8:41 pm.

V4 Power Posts: 94 Group: Members Member #3,161 Joined: August 31, 2008	I'd check your front wheel bearings first before complicating things with your propshaft, the symptoms of brakes and steering point to that end of the car, HTH

Hot Lips Posts: 3,302 Group: Members Member #2,380 Joined: March 6, 2008	A wheelbearing would have to be totally destroyed to produce the sort of vibration described! A prop or driveshaft fault would produce a vibration felt through the whole car!

Sales Rep Posts: 1,815 Group: Members Member #1,387 Joined: June 9, 2007	We also cannot rule out the propshaft couplings, as they wear the shaft can run in an elliptical motion as it sags. Doesnt really explain how it quietens down. To check the front wheel bearings you need a magnetic base and DTI. The rears arent adjustable. Another thing worth checking is tyre pressures and tyre condition.

The steering box is on the drives side too! Maybe worth a quick visual check?

Sales Rep Posts: 1,815 Group: Members Member #1,387 Joined: June 9, 2007	Yes, sagging engine mounts may resonate but during cornering the engine may shift away from other, static components. Its one of those "very to diagnose by post" problems, but a fistfull of ideas will save you a fortune.

Hot Lips Posts: 3,302 Group: Members Member #2,380 Joined: March 6, 2008	Is there any noises (clonks etc) when drive is taken up? When you got the car (as you said problem has been there since) did it have either a damaged wheel or had a new one fitted? OR Has the car been used hard (high revs & clutch dropped starts etc!) EDIT: Another little test is when you've got back after a longish run, check each wheel temp with your hand! Edited by Stempies, Sun Jun 21, 2009 10:07 pm.

Hot Lips Posts: 3,302 Group: Members Member #2,380 Joined: March 6, 2008	Only reason i ask if wheels have been changed/damaged is one may have been smacked into a kerb sideways and bent a half-shaft!

Moar Bass! Posts: 5,048 Group: Members Member #456 Joined: August 14, 2006	ahh gotcha... its a possibility esp considering the condition of the car when i bought it if its not fixed by retro time i may have to take a few of you guys for a spin in it to help diagnose it



CrysAk	Wed Jun 24, 2009 4:07 pm Post #21
Moar Bass! Posts: 5,048 Group: Members Member #456 Joined: August 14, 2006	some more info... when i got my tracking/wheels aligned there was 2 issues which couldn't be done properly.. which were the following.. Front Left Caster @ 1011' (should be 1025' - 1125') Rear Total Toe @ 012' (should be 015' - 035') where * = degree does this verify anything?

And with the back it sounds like someone has been 'Kerb nudging' with the back wheels a bit too heavy. Needn't be but could be.

Moar Bass! Posts: 5,048 Group: Members Member #456 Joined: August 14, 2006	thanks done some digging and ive come to the conclusion its most likely the front right wheel bearing, will be going for a spin tonight to confirm this

Resident OVP Expert Posts: 2,697 Group: Members Member #11 Joined: November 6, 2005	Also bear in mind a bad engine mount on one side will cause a vibration which disappears when you turn the same way.

Moar Bass! Posts: 5,048 Group: Members Member #456 Joined: August 14, 2006	idd, the pitch/tone changes depending on speed though rather than revs in this case,

Bolide Posts: 192 Group: Members Member #3,828 Joined: February 11, 2009	W124: As the engine mounts sag the engine drops up to an inch and a half. This stresses the front prop doughnut. As the diff bushes wear the diff rotates on its mountings and this ovalises the input seal, causing leaks 190E: probably exactly the same With most W124s there are multiple faults. With 190Es being older there are probably even more. The most common things I replace during W124 estate prep are front ARB bushes, engine mounts, front prop doughnuts and balljoints I would suggest that, if you don't know whether your balljoints have been replaced, you just replace them Nick Froome www.w124.co.uk

Moar Bass! Posts: 5,048 Group: Members Member #456 Joined: August 14, 2006	thanks guys if i get no luck from this ill take those routes this happened on the EVO1s aswell so i doubt its the wheels, also what with them being balanced recently this also rules it out

Member Posts: 336 Group: Members Member #3,735 Joined: January 16, 2009	Only skimmed through this thread but have you checked the wheels are balanced? Mine vibrated at around 90mph, turned out the front wheels had been balanced on the cheap, a dynamic balance at Kwik Fit for �10 sorted it
