HELP!!!! My 1990 LS400 has 170k miles on it. Just recently, my rear end has been vibrating at high speeds. It is intermittent and my mechanics have had trouble replicating it on their test drives. When I slow down and then stop, and then set off again at low speeds, the vibration goes away. But when I go back to 50+ MPH there it is again. The first time it happened, I thought I had a flat tire. Then I thought it might be a wheel bearing but they now tell me they believe my ABS is switching on when it shouldn't be. Can I just disable the ABS and do without it? I don't feel I need ABS but don't want to do anything dangerous. If it's OK to disable, how do I do that? Thanks for expert feedback from the gurus out there!

SOS. Help!! Any advice from the Lexus gurus??? The stock Pioneer radio for my 1990 LS400 is not working. I bought a replacement on eBay and swapped it in but to no avail. Same symptoms... The power is on because the display lights and it tunes to a station but there is no sound. Below is more symptom history and details. How do go about determining whether it's a) both radio heads are bust, B) the amplifier is kaput (and by the way, where is the amp?), maybe c) an absent security code is keeping my radio from working, or d) none of the above. The history of failure: First, I had to coax the radio on occasionally by pressing the on button repeatedly before it would go on. Then it would go on after repeatedly pressing the on button but the volume was faint, almost inaudible. Now nothing except the display light witht he tuner showing a legitimate signal station. Thanks!!!
