have a bad shaking on my front right pass side of car and rear shakes as well
change rear diff a few months ago, changed tranny mount, engine mount..
car has 80k miles and feels like its right front axle. cost new is $1200.. but i am not sure.
i am getting no noise just rubing sounds on right site and can shudders a lot.
when i pick up speed it is really bad.
any ideas? if its the axle has anyone changed them before? is it easy to change? dealer cost for part is around $1400 .. i am new to site so any help i appreciate.. i am pretty handy and change a lot of parts on my other merc 2005 ml350.
thanks

have you ruled out tire or wheel problems already? Maybe rotate them since all 4 are the same on the 4matic and see if problem follows.

ooh yes new rims and tires and force balanced.. and few weeks ago..i took car to 2 shops and both said its right axle after they also said mounts.. which i replaced.

i want to try and get a after market axle if that makes sense.. but cannot find any for 4matic.. also maybe there is used ones i can get for now? how had is it to change the axle on the 4matic?

Wheel bearings? If you jack/raise the vehicle, does the front right (or any other) wheel wobble when applying twisting force side to side?

gkeane2

i did try that ..no nothing wobble.. i get a wooo. woo. feeling in steering when i drive slowly.. when tire rotates.. seems to be coming from right side.. and steering vibrates.

gkeane2

when i apply brakes no wobble just the rotation shaking

gkeane2

the whole car vibrates and shudders.. not sure bearings would cause that?
