Hi all,
I have recently bought a 2001 ls430 and it had a couple of minor issues which I have now resolved.
First I noticed that the drivers window would not always fully close, second the steering wheel would shudder as it would retract.
Both of these problems were fixed by some silicone spray, I used one with a straw so I could easily get it on top of the steering column and around the edge of the window frame.
I did see the steering problem on a forum and the advice was to take the steering apart and grease the parts but the spray does appear to have done the trick so far.
Hope this helps someone.
Steve.
