    Probably late to the party but pulsating especially on the patrols tend to be from the rear.

    I had it and was annoying as hell.

    Both patrols from the rear.

    Actually even my prado from the rear.

    New rotors and its been great

    You're not the first to suggest that. Something I never even thought about. Might have a look later.

    I also assumed, it possibly may have something to do with the death wobbles I've been having...
    I don't know, brain storming, a disc off balance sending a wheel out of whack at certain speeds.

    But my wobbles now entirely gone away, without me touching a thing. so can't even diagnose that now...

    Hey Hodge.

    Was it death wobbles or more vibration shimmying?

    I had vibrations shimmy when I bought the cheapr COmforser CF3000 35 inch tyres.

    They looked great but I couldnt balance them.

    Was scratching my head and losing hope.
    I swapped over to Kumho 35 inch and its been great ever since.

    This especially I double checked all the bushes from a suspension place too.
    Engine mounts for engine and transmission mounts are new

    All bushes double checked. Even had new bushes ready to go in!

    Damn tyres.

    Hmmm unsure of the difference there mate. lol

    (when it does happen)
    85-90km/h the steering wheel starts a rhythmic shake. Well, not just the steering wheel, it's more like the whole front of the car. It's not SUPER bad, but it is very annoying and forces me to get out of that speed range ASAP.
    First things I checked were missing weights, and took wheels off and looked for clumps of dirt/mud stuck somewhere which may send it out of balance but found nothing obvious.

    But before I even got to inspecting further like bushers etc, it just stopped doing it.. So bugger me , I don't know what the hell is going on. I sincerely hope it does not return. lol

    lol

    What you describe sounds like shimmy. Death wobbles you would know. Whole car will be so violent that you must stop! Its like you going on massive pot holes or corrugations

    Probably was a balance issue with wheel so when you place it back on properly it went away.
    I noticed with 35 inch tyres for me. A wrong cheap brand or something slightly out. It will definitely show on 35 inch tyres while smaller tyres you can get away with
    faults or imperfections more.


    I learnt this by running cheap 35 inch comforsers. Brand new. I was so doubting myself and thinking maybe all 35 inch are hard to balance.
    Then switch to KUMHO mt51. Smooth as.
