Does this really need to be changed at 60,000 miles and can you use standard aftermarket LSD oil?

Replying to: rogerconcertin (May 05, 2009 5:43 pm) Mine doesn't have RWD or LSD, so I haven't changed mine. But I can't imagine it's very hard to do, and would probably do it myself. Are you changing the tranny fluid and PS fluid, too? Vehicles like the RX, and the RX 300 in particular, run fluids "hot" and the fluids break down and no longer efficiently work, and lots of wear results. |

Replying to: rogerconcertin (May 05, 2009 5:43 pm) The RX300's and (maybe) the RX350's have a VC, Viscous Clutch or Coupling, supposedly to distribute engine torque to the rear with semi-continous front wheelspin/slip. For '01 and after TC, Traction Control, is used to make the VC pretty much totally non-functional so it was dropped entirely for the RX330 product run. As to the RX350 Lexus marketing materials state that it has a VC again but the factory service/shop manuals do not bare this out. In any case the VC fluid is hermetically sealed within the clutch case and cannot be serviced. If you're asking about the PTO lubricating fluid in which the VC runs then there is NEVER a need for changing that fluid, as indicated in your owners manual, since there is no stress within the PTO that would warrant same. I now have ~75,000 miles on my '01 F/awd RX300 and nothing has been done under the factory recommended scheduled maintenance requirments other than oil and filter, air and oil, changes. In order to test the functionality of the VC in my '01 on a 4 wheel dyno I had to disable TC and even with than no more than 25% of the engine torque was routed to the rear driveline. Which is probably why the 2010 RX350 has now adopted the more functional F/awd system the Ford Escape/Marinerand the Mazda Tribute/CX-7.

I have a 2002 RX300 with 126k I want to do the timing belt and water pump. It runs great, so is there anything I should have them do while things are apart. For example: starter, alternator. What is the mileage most of you are getting on those two items? I am not worried about plugs and tune up yet since it runs fine. Ken

Replying to: tidester (Jun 04, 2009 3:25 pm) How did you resolve your issue?

Replying to: la4mead (Jun 04, 2009 10:17 pm) I got better response after the resolved post than the original one. lol Not really a solution, rather a decision to go ahead and do the belt and pump now. And wait on the starter and alternator. Should have just said what I was going to do rather than resolved, sorry. Ken |
