I have a 99 rx 300 with 245K on it. The current engine has 150 K on it. The engine was replaced due to oil sludge issue which caused engine failure @ 95K. Asside from that I have had a few issues but mostly routine maintenance. See below for a lits of things I have replaced and cost - I did all labor myself.
Issues I have had: Strut mount bearing replaced
TRANSMISSION Failure @ 200K for me - 4K replacement
Lower COntrol Arms @ 230K - 500 Dollars
Ball Joints @ 240K - 100 dollars
PS Rack @ 244K - 400 dollars
Coils - Replaced 4 of them so far - 75 each
O2 sensors - 100 each approx.
Exhaust Gasket - 30
Battery - 100
Bearings - 100 each
Lights - bulbs only
Transaxle seals - 65 each - seals transmission fluid at cv insertion
Other then the transmission, most of the things I have replaced are normal wear and tear for vehicles. I have gooten over 200K in mikage before I had to replace any major parts. The tranny will go out almost gauranteed unless you have regularly flushed it etc. That is the only red flag really. All and all, I have spent about 10K over the past two years to replace thigns - mind you I DID ALL THE LABOR. At this point I have spent too much to sell it, might as well drive it until it fails. It has been a good vehicle espeecially considering the milage I have on it.
I also do all my own work on my 99 RX AWD. I have 145k on it and it needs all 4 struts. Do you recommend that I just go ahead and replace the front upper strut mounts? How much were they and is it just a simple repair as it looks to be?
Thanks!
