hi i ve question for experts in car , i ve 08 tl , while driving when i change lane , left to right lane i feel shake on passenger rear wheel, plz give me suggestion , its shock, or control arm ?

 

Need to get it up in the air for an inspection/exam.
Check for any looseness as well as the stabilizer links.
Also, once in the air, raise the wheel assembly with
a jack so the suspension is loaded, as if it were sitting
on the ground and do the check.

 

There could be many things. At this time of the year, I should ask - did you recently put your snow tires on? if not, jack it up and check for looseness in stab links, stab bushings etc.

 

no , i did not put chains on tire.

 

A bent wheel could cause that issue.Also uneven tire wear.

 

how many miles?

Worn/blown shock, bad alignment, bad tire wear, etc. Lots of causes, need more info.
