Hi everyone thought I would update about the problem I posted, I collected the vehicle today from Lexus at Coventry, they spent most of yesterday tracing the fault, the located the fault and have repaired it. The cause for the vibration etc was a faulty ABS sensor, it had corroded and the air gap was wrong, this was sending the wrong info to the ECU, they also adjusted and cleaned the parking brake. They managed to clean the ABS sensor instead of just replacing it like most dealers would do. It is now perfect again, and a pleasure to drive like an RX should be. I have nothing but praise for the service department. The price they charged me was also very fair. The only negative comment is a salesman offered to do a deal for an 06 400h they had on the forecourt for £22000, the cost to change £19000, which means only £3000, for my 51 plate Rx 300 Navigator with full lexus service history and 58000 miles, the vehicle is immaculate. I will now be keeping it a long time. I cant believe thats all its worth. Im sure Boxbrownie will be interested in what was causing the problem. I hope my update will hopefully assist another owner that has a similar problem. Regards Grant

To update you and in particular boxbrownie, my mechanic today stripped down all of the nearside wheel and caliper including the parking brake etc and couldnt find any faults, what he did find was that he could move the drive shaft clockwise and anti clockwise within the splines and he is not sure if that should be the case, I cant imagine the movement should be there, If I need a new driveshaft, I have located a company that sell the entire shaft with CV joints for £179 + the dreaded vat. Any thoughts please Grant

Thanks for that boxbrownie, having read your post I tried something which Im sure would not be recomended but I applied the parking brake only one click, and drove the car, guess what, none of the noise, vibration or other problems, I then fully took off the parking brake and the noise and vibration returned, not sure if it was co-incidence, so will try it out again over the weekend, if that does solve the problem I can only think the by partially putting on the brake it takes up and slack and holds the shoes off the drum !!!!! just a thought. I have spoken to the local Lexus dealer and they have said, now you mention it we have had problems with parking brakes on mark one models !!!!!! I will let you know the outcome. Thanks again Grant

I have owned my 51 plate Rx300 which has 56,000 miles on it for over 12 months and I love the car to bits, and I have to say it was you guys on this forum who gave me the confidence to buy it privately after being let down by a Lexus dealer, This is my first post and would appreciate your help, for 12 months it has been perfect, but now when I pull away slowly I get a grabbing sound and vibration from the rear of the car, and the car seems to be pulling to the nearside, it happens more when I turn right slowly or straight ahead, but never on a left turn, it dosnt happen all the time, and it only happens if I pull away slowly, when I get up to about 7mph the noise stops and it drives great, I first thought it was a brake binding, but can now discount that, as the calipers are free and also when its in drive it moves slowly forward, and only happens when I start to accelerate, a mechanic (none lexus) has looked under the vehicle when I pull away and he can see the N/S rear driveshaft vibrating, a call to a lexus service centre has suggested it could be either a wheel bearing, the CV joint or a universal joint on the propshaft. All sound expensive except the bearing, has anyone else had this problem ? Grant
