    The e-brochure for the AWD 2005 RX330 at indicates that the VC, viscous coupling, is back for 05.

  • what is viscous coupling?
  • I was coming back from a store, and I noticed a nail on my tire. The nail appears to go at an angle, but not into the sidewalls.

    So, I drive back home and try to figure out how badly damaged the tire is. I got some pliers and pulled it out. The nail was about and 1 inch long. The surprising thing is that the tire didn't deflate at all. I checked it out the next day and the tire seems to be find.

    I will eventually have to get a new tires, my tire tread is showing signs of wear already. Anybody know a good place to get some new tires. I have the 18 inch rims. The dealer charges $215 a piece for Michelin tires.

    Sorta like an LSD, limited slip differential but done with molasses and clutch disks.

    Dear Mr. West,

    Thank you for contacting Lexus Customer Satisfaction regarding the 2005 RX 330. We appreciate your interest in this vehicle.

    Per our technical department, the 2005 RX 330 does not have a viscous coupling LSD. The vehicle has adopted a full-time all-wheel drive system. We are sorry for the misinformation.

    If you would like to discuss your concerns further, you can also reach the Lexus Customer Satisfaction Department at 1-800-255-3987, Monday through Friday, 6:00 a.m. to 5:00 p.m., Pacific Time.

    The current 2005 RX330 e-brochure indicates that the 2005 AWD RX330 has the viscous coupling again.

    Is this actually true or is this a typo?

  • cotmccotmc Posts: 1,081 is currently selling the 18" Michelin tires (for RX330) at $128 each. Considering you'll pay a small additional fee for shipping and for mounting, you might see if a local chain can come close to matching tirerack's prices (i.e., $160 or less, per tire, "out the door" -- after adding all the dealer fees and taxes). If not, have no fear with tirerack. I've used them several times, and they seem to be very popular within these automotive enthusiast forums.

    PS: I would never pull out a nail on my own. Most tire dealers (incl dealers that do not sell that brand of tire) are willing to assess and repair a flat. For about $10, they dismount the tire, examine the puncture, and apply an appropriate plug.

    A few of the big chains, at least out West, will do that free - I've had several flats fixed gratis at Les Schwab, and I think Big O does the same.

    Cotm is right about not pulling out the nail. It is the only thing that might be preventing rapid deflation of your tire.

    Nowadays, many places don't even dismount the tire. They simply insert a plug, and off you go. It takes all of ten minutes.

    Hi, ladyofluxury. Glad to hear you are back. I guess you must have been busy keeping us safe here at home, through all that's been happening in Iraq.

    Good to hear you are enjoying worry free times in your RX. Your husband can't go wrong with either the GS or the LS. I know the LS430 is a sweet ride. The GS is due for a facelift next year. You might want to wait until you see one. Good Luck.

    Steve: I don't know much about Les Schwab, but it sure seems his brother Charles isn't doing such a great job of keeping things inflated during the past few months. And to add insult to injury, Charles charges $19.95! ;-)

    I think Les's financials are better, but he's selling something tangible :-)

    Does anyone where to get a good deal on OEM mudguards? The local dealer part dept. price for 127.30 for the set (front & rear mud guards)

  • Hi Everybody,

    I'm checking into the RX 330 and was wondering if someone could give me a measurement of the cargo floor length when the back seat is folded down. I haven't been able to find this measurement anywhere. I have to carry a piece of equipment from time to time and this measurement is important as to whether the RX330 would work for me or not.


  • cotmccotmc Posts: 1,081
    The cargo floor length will vary a little based on the location of the front seats. For my normal seating position (I'm 6 ft tall), I measured 71" along the cargo floor from the back of the driver's seat to the rear door. (In all honesty, I could easily move the seat forward at least another 1", maybe 2", to provide a little extra cargo space, when needed.)
    This measurement drops by 3" if the cargo is greater than 3-4" tall, due to curvature of the seatbacks. This measurement will drop a little further for tall (>2ft) cargo, due to the curved rear hatch door.
    Hope this helps, and hope these measurements work for you.
  • Thanks for the reply!

    I saw a recent post referencing active steering on the RX 330 for 2005. I saw no reference to this feature on the Lexus website. Can anyone tell me what it is and how it affects the drive. I love the look of the car, but when I drove a 2004 I was somewhat dissappointed with the cushy feel. I did not get a strong sense of road feel that you get when driving a BMW. Does this feature (if it exists) change that? Does the optional air suspension add anything to the sportiness of the vehicle. Any thoughts or comments are appreciated.
  • wwestwwest Posts: 10,706
    BMW or MB, don't remember which, has added an open differential in the stearing box with a servomotor at the other input, opposite the stearing wheel shaft.

    The idea is to use the servomotor to vary the stearing ratio as circumstances warrant. But the big part of this "invention" is to be able to counterstear against your input should the vehicle not be able to remain stable with your wider, unmodified, inputs.

    Touted as being faster reacting than the current, VSC, PSM, etc, brake modulation method.

    Sorta like that airbus that went down in the french forest years ago, the fly-by-wire system decided that the pilot was asking to climb too rapidly and so it "counter-steared" the elevators to prevent the airplane from climbing above the trees.

    Gee, the computer didn't see those trees!

    Not saying that Lexus' active stearing is the same as above.....

    You must have missed my other reply about the Airbus Wwest - I think your version is an urban legend.

    It was certainly the pilot's error to have gotten into a circumstance wherein he needed more climb rate than the airframe could produce without be overstressed, having the wings buckle...

    But in the end the simulations indicated that although the airframe would have likely been severely overstressed to the point of being scrap metal the likelihood that, had not the firmware limited the climb level, all would have survived was confirmed.

    Regardless, I'll always make my own call to recover from a skid, if I crash it will definitely be pilot error.

    If you like I can arrange an interview with one of the Boeing engineers who was key to writing the specifications for the 777 fly-by-wire flight control firmware and/or one of the QA folks who was responsible for confirming that the 777 firmware had no such limitations, intentional or other wise.

    No, the airbus firmware flaw is based on actual fact.
