Lexus RX330 Have 2004 Lexus RX330 w/ around 250,000 miles. For

Resolved Question:

Have 2004 Lexus RX330 w/ around 250,000 miles.
For awhile now the steering wheel and vehicle shake when the brakes are applied at high speed. Have had rotors resurfaced and even replaced (but not with so-called Lexus rotors).
Was told by guy at Lexus place the only remedy is to let them replace the rotors with the original OEM "Lexus" rotors, that other rotors are too thin or something and will always give me trouble.....and they want to charge me a totally outrageous price for parts and labor to do the work themselves (surprise, surprise).
Is replacing the rotors all around on this vehicle something I could do at home?
Why can't I order good, inexpensive rotors online that will work?
Do you have any suggestions on the type rotors to order and where to get them?
Please help me save a ton of money here.
Thanks so much!

Hello there!

My name is XXXXX XXXXX I can assist you.

Since the steering wheel shakes when you step on the brakes, chances are it is only going to be the front brakes that are at fault. However, this does not necessarily mean that your rear brakes are ok.

YES.. you can do these brakes yourself. However, this would require the right tools. I would strongly recommend to get high quality parts for your vehicle. IF not Original Equipment, at least some very high quality parts. The cheaper the parts you get, the more chance you will have the same problem you are having now.

That was not exactly as detailed an answer as I would have anticipated.

I would appreciate your advising me specifically on the following:

1. Where is the best place (and prices) to order the rotors of which you speak?

2. What rotors should I get (specific manufacturers and rotors)?

3. What is the procedure for replacing the rotors myself (how do I do it)?

I look forward to your response, and thank-you!

Do you want me to suggest a store or a site on line?

What rotors should I get (specific manufacturers and rotors)?

This depends on your price range. I can get you the price and part numbers if you would like.

What is the procedure for replacing the rotors myself (how do I do it)?

I can get you the procedure from the manufacture if you would like...
