Vibration

[Luki]

Hi when I'm driving on the motorway at 80mph or more the car is vibrating/shakeing, it's coming and going any ideas please

Hi Luki, when was the last time you had all four tyres balanced and wheel alignment done?? would also help to check your psi on tyres to make sure none of your tyres are under inflated. i think it shoujld be between 33 - 35 psi... might be worth having all four tyres balanced and wheel aligned and see if it makes any difference!!

just noticed i have the same 300 as you silver Aero 18'' with sport (yellow) fogs :winky:

Thanks noby76, il get that done soon as! Hope it sorts it coz I like sitting at 100mph in peace :-)

There fantastic cars arnt they it's just lacking a turbo pull

[noby76]

tell me bout it mate 100mph feels like 50mph with no stress to the engine!! and yes with a turbo feeding the 2JZ with more air that M5 driver in my other thread would have been sucked and blown out from my exhausts

[Luki]

Lol yeah iv been following that thread

Wanted to ask are u a machanic coz u have a lot of knowledge

[noby76]

no mate!! am far from a mechanic...am into cars so just know a little bit about them...

[Luki]

Did u used to have a mark 4 golf and did a group buy on the anniversary kit??

[noby76]

no mate! my previous car was a V6 ford cougar another Range Rover sport killer on the M1 but wont bore you guys with it either !!

Iv just got all the caster, cambers and toes and allighnment done but it's still shaking, the mechanic said that the tyre have got waves on them could that cause it

[noby76]

if you had all four wheels balanced aswell then wont have a clue mate!! might need to the car to a suspension specialist for inspection..

[jfatboy]

Possibly true. You should have all four wheels rebalanced as a starting point. Once had similar problems when wheel alignment was needed and was put off for far too long, causing that sort of wear/problem with tyres. But it is still necessary to eliminate worn/loose: engine mounts, wheel-bearings, bits of suspension or steering etc. A shame you couldn't temporarily swap a set of tyres or wheels to prove the point.
