In all my years of using forums, this thread proved to be one of, if not the best I've ever encountered.
I have a 2005 LS 430 with 156,000 miles.
My right front bearing failed. At first I thought it was an airplane flying overhead. But when it didn't go away, I got out and inspected the wheel. Finding that the tire was just starting to separate on the edge of the tread, I took it into my local tire store for new tires.
Much to my chagrin, the noise remained. I turned to the forum and found exactly what I was seeking. The description of the problem was dead on, and the detailed photos and instructions were clear. As I read deeper, I discovered the cause of the failure.
About three weeks ago, as I was traveling early in the morning, I was instructed to get into the left turn lane to a local freeway. The only problem: I got into the turn lane too early, for another road and suddenly, at about 45 mph, I hit a curb and went back on the grass for about 100 feet before the real turn lane began. Luckily, the curb was beveled, or I would have taken out the whole front suspension. I was certainly awake then!
Thanks to all the great contributors to this thread. This is the second time I've solved a major repair problem using the instructions I obtained from using the Club Lexus forums. I estimate this has saved me over $1,500 in repair costs. As you know, if you own a 430, it's never a cheap fix!
Kudos too, to the folks at Lexus of South Atlanta. http://www.lexussouthatlantaparts.com
Not only did they offer good prices, I was able to speak with them and they gave me tips on how to make the job easier. I highly recommend them!
Like many of the comments, I probably will be doing the left hub soon. But when I do, I have complete confidence in doing the work, thanks to Club Lexus!
