I purchased a used LS 460L w/ 60k miles after a few months noticed a rumbling sound front end noise took it to dealer was told upper and lower control arms and bushings needed to be replaced at a cost of $4,000. Looking for options have a friend with LS460 w/90k miles no problems must be the L version issue ???

 

control arms are a known issue and many of us had them replaced. It is covered by CPO and 3rd party extended warranty companies. You can order them online and have a shop replace them for a little cheaper. You missed about 3 threads already talking about this
