2003_GX470_2Krpm but slow to pick up speed
I would like to post this performance issue on my 2003 GX470_79Kmiles which happened on the freeway yesterday. The sequence:
1) During start and at idle/stationary, the rpm shoot to 1100rpm and stayed there for a while, i would think that it was normal since the engine was still cold.
2) Drove to the freeway, I noticed that speed is very slow to pick up. My normal driving experience was that at close/equal to 2000rpm, the speed usually at around 70-75mph. But there was a considerable reduction of speed at around 60mph at almost more than 2000rpm, plus a buzzing engine noise. I tried to really rev-up the engine but very sluggish to pick up the speed not even close to 70mph.
3) Drove the car to lexus shop this morning, top speed of 60 to 65mph and tried to rev it up to plus 2000rpm to pick up speed, but the engine noise is very abnormal.
Any comments or experience of this kind of problem, appreciate much.

There was no engine light alarm. Lexus dealership found the front driver side wheel bearing failed...OUCH!! This was causing the noise and not picking up speed, basically it just being carried as an extra load. The axle is okey but power is not transmitted to the wheel, at 80Kmiles to fail is kinda questionable. I decided to replace both sides, new hub and bearing assembly of lexus parts.

Might want to go ahead and change out the front differential gear oil at the same time.
It is strange for the bearing to fail at 80k miles, but sometimes stuff just happens...

Lexus dealership replaced both sides front wheel hub/bearing assembly, per my instruction, and it corrected the problem...at a premium repair cost...OUCH!
