    Cruise Control + Vibration at 110 kmh.

    Hey guys,

    (note - don't use my how to guides,, lol)

    There are a couple of irritation issues with Andora (D2 V8 Auto) that I haven't been able to either fix or work out *why*.

    The first problem is the cruise control which I have tested checked and re-checks dozens of times. It works, but when cruising on the motorway it seems to hunt through 4th and OD constantly. It's irritating, it's not major but it's a constant hunt *click change a few hundred revs, click change* - you expect it on hills but not a flat motorway. Mechanics can find nothing.

    (I noticed this happened all the time in my 2006 Jeep and had the service people check it and all they said was *that is what it does* suck it up and put up with it.)

    Am I being pendantic or is there a problem?

    The second issue is with vibration, it seems that again on a motorway I can't do 110kmh without the car vibrating noticeably. I've checked bearings, engine mounts, wheel alignment and all the usual suspects but nothing appears to be out of order.

    Speed up 10kmh it goes, slow down 10kmh it goes away again.

    Again is this just the D2 or is there somewhere else I am not looking?

    Cheers,

    mx

    Was the rotoflex one of your usual suspects? I had recently removed the rear prop shaft and noticed a vibration at low speeds and turned out the prop shaft was sitting to far from the diff flange so the rotoflex was being stretched. , also if you have removed the rear prop shaft recently, did you mark it so you knew which way to reinstall it? I've heard if they're put pack wrong it can cause vibrations, I ended up rotating mine 180degrees to get rid of the low speed vibration and she's back to normal (in regards to vibration). There is heaps of info on here about vibration in D2's so have a search.
    Even go through google and put aulro in "quotation marks".

    There is a simple cruise control adjustment procedure in RAVE, if you have not already tried it.

    I agree with Trevor, although I have not experienced the vibration issue myself, from what I have read, the rotoflex is worth looking at. I understand it needs to be removed to properly inspect its condition.

    I'll give that a crack again, thats not to difficult. (cruise control)

    The business with the rotoflex I'll pass onto the mechanic that swapped the suspension over, although both of these things were issues before - the vibration not as bad.

    Yes I did try search but for whatever reason, half the time I end up either no information or stuff that is irrelevant to D2's. Google + Aulro seems to give me better results.

    I'll post up what I find out.

    Thanks guys,

    Another suggestion for the vibration symptoms you describe would be wheel unbalance. Have they been changed recently or perhaps a balance weight has fallen off?

    Regards,
