120 series rear suspension rock and rolling

[woods Lurker Find all posts View Profile Close woods]

Just wondering if anyone has fitted an OME 2 inch lift kit to there 120 series prado and had issues were the rear of the car feels like its rock & rolling alot as if the car were only riding on the springs and the shocks were not there. The car has done 35000klm since they were fitted 18months ago. The car has also had new BF all terrain tyres fitted at around 20000klms ago but i have had them rebalanced and the problem didn't change. Or is it possible with the extra height in the rear end of the car that this could be a normal symptom. I don't recall it being like this after i drove it out straight after the kit was fitted. Anyone with any info would be great. Cheers

you mean its rocking side to side?
if so I would check your sway bar.

I run OME suspension and BFG tyres and haven't experienced anything like you describe. I would say its not normal.

What are all your suspension bushes like? Also what tyre pressure are you running? Which springs have you got and how do they compare to your normal loaded weight?

Are the shocks leaking?

When riding in the rear of the car it almost feels like you could become sea sick for example.A couple of people have commented on it and you feel it when your the driver mostly it's like your forever correcting the steering if that makes sense. Thanks

amts i have had the rear end of the car checked over by an automotive mechanic and the shocks seem ok. The lift kit in this prado from OME sits very high in the rear compared to the front i thought maybe that had something to do with it. Thanks

I have the OME kit with 100,000klms on it and no probs except the front is getting a bit soft now and nose dives under heavy braking.

Are your bushes ok? They haven't been chewed out?

AJ120 thanks mate , i couldnt say what springs were fitted mate i was up for shocks at 120,000klms and thought id have a 2 inch lift fitted at the same time, It does sit fairly high in the rear compared to the front and it almost looks like the front has sagged or the rear is to high. I honestly thought it was the tyre id had fitted to start with so i had them rebalanced but it didn't seem to make a difference. I think i will get ARB to look at it and see what they come up with. Thanks for the reply mate.

I had a mechanic have a good look over it mate and he tells me it was all good, the cars done 150000klms so i thought that may have been on the cards to start with. Thinking i get ARB to check it over for a second opinon maybe. Thanks for your replay mate. cheers

Take some measurements from the bottom of the rim to the guard flare like in the photo below




Let us know the front and rear measurements and we can give you an idea whether the rear is high or the front is low or if they are ok.

Cheers Andrew

Thanks andew i will do that mate and get back to you with some measurements. cheers

Hi Andrew the measurements are 835mm in the rear and 765mm in the front. I'm not sure if that's ok mate or not. Thanks again mate. CHeers.

70mm difference between the front and the rear is way too much. The geometry of the car will be out which will be contributing to the handling (or lack thereof) of the vehicle. 30mm difference is about what there should be woods

Yeah Craig is on the money, standard measurements are usually around 750 front and 780 rear. So your rear lift is a bit above what I would expect and your front barely has any lift at all.

Don't know that those measurements shed any light on the exact cause of your issues but I would certainly be asking some questions of ARB.

I am assuming you have spring suspension in the rear, that is you don't have a Grande with air bags suspension, correct?

Cheers Andrew
