Hi guys
I have an auto TD with OME Suspension & AT Tires & have noticed there seems to be a vibration / shutter on take of. It only happens on the initial take of.

I have put in into 4X4 and the vibration disappears.
I have talked to the Service people at Toyota at they advised me that the vibration is caused due to the suspension upgrade (Firmer suspension) & AT tires

I have not tried if the vibration is there when it is fully loaded yet

Has anyone else noticed the same thing. What are your thoughts?

i have an auto TD also and my girlfriend complained to me of the same thing. (she has been driving the car as i lost my licence) the way she described it to me was that the brakes were shuddering on take off. but of course when i was listening for the sound it didnt happen. at the time i put it down to her lack of knowledge but now you have me worried. i dont have suspension upgrade or different tyres though.
we are going out in the car on thursday night so i will report back to you on friday if i here anything suspect...Glenn

I had a similar concern when the car had relatively low kms, and was only noticeable on the smoothest of roads on initial takeoff, had one toyota mechanic take it for a test ride with me and he couln't pick it. I then took the head mechanic out and after some time he said it was the torque converter and it was entirely normal. That was 000's of kms ago and now don't even notice .

thanks for your response guys, good to hear its not only me that notices it

I have the shudder too but only noticed it after I fitted the OME 50mm lift suspension. Mind you, i only drove it 15km without it. Is this because the transfer case needs a plate fitted to lower it. I had a much worse but similar situation on my KJ Jeep (I know, I've seen the light) and the transfer case plate fixed it. I fear if I take it to Toyota they will just blame the suspension and ARB has just thrown its hands in the air??

Mogofo

Yeah I went to Toyota & they did just blame the suspension as it is an aftermarket one
And ARB said there is nothing wrong
What did ARB tell you
Have you tried putting it into 4X4 (It seems to disappear)
Mines going for a service next tuesday & I will ask them to dig a little further to find the problem

I have heard of this before, think there was another post on this subject a while ago.

I think it is the new angle the uni joint is forced to work at with the lift. I have heard some fit spacer plates to change the angle of the diff to better suit the tail shafts new angle ?

Putting it into 4x4 removes some load from the rear uni (now sharing load with the front diff) reducing the shudder effect.

If the shudder wasn't there before the lift but is now you have to ask what has changed, it can only be that one thing lifting the car.

I had OME fitted as well but do not get the shudder but mine was lifted/settled to 40mm in the rear (medium springs) mine is a manual so isnt subject to constant loads like an auto supplies either

Maybe the extra 10mm is enough to upset the running angle of the uni, I could be miles off as well, 50mm doesnt seem that much ?

Hi Everyone,
Yes I have the same shudder on take off and in deseleration to stopped( the last 10km/hr. It was thier in a very mild case prior to lift and worse now).

It was easy to tell before the lift that the issue was the tail shaft joint. Toyota greased it at service and it went away and only came back close to the next service.

Now ( after lift ) if I grease the tail shaft joint that spreades the shaft it goes away but comes back in 1500km.

What the answer is I do not know. EFS found this issue with early testing and do not have an ansewer. Only auto's have this issue????

Regards,
Camwill69

I have a TD Auto with ARB OME Lift and I havn't noticed any shudder when starting off.....
Sometimes I notice something when slowing down, but I thought that was just the Auto transmission coming down through the gears....

I to have just had ome lift done by arb and have noticed in take off a shudder from the centre of the car mentioned to arb on 500km check up and said never heard of it before as they all say. Also recall it on our sr 05 lux when i had an extra leaf put in and reset.

by **Smithyworld** on Fri, 09 Nov 2007 9:52 +0000

Brett B is spot on. It is too do with the angle of your uni joint most likely. As you raise the suspension in a car the uni joint angle becomes sharper and there for the components do not mesh as well giving you the shuddering. As Brett mentioned putting it in 4WD takes some pressure off the rear therefor reducing it.

In a long wheel based vehicle it usually isn't too bad. I have my rig lifted about 60mm and I don't notice it. Although in saying that I was used to it happening in my short wheel based JEep wrangler with nearly 5 inches of lift.

The other possibility is your tyres. Are they quite knobly? I have MT MTZs and at take off and when slowing down I feel the vibration as the tyres slow to a speed where the knobs cause a shuddering. Only last for a few seconds though.

Dave mate,
I thought I was the only one.

Had initial 30mm rear lift(70mm front) by suspension shop and noticed small shudder on take off and slowing down (at 10km to 20km).

Diff lock was done a few days before at arb.
I assumed it was the diff, arb said its the suspension.

Wasn't happy with the lift anyway so I went a full 3"
above standard right round.

This made it even worse, i'm talkin' really bad.

Then he put in some wedges between the axle and leaf to tilt the axle up slightly in line with the tail shaft, 2 degrees helped a bit so he swapped it for 3 degree wedge and put some washers in to pack the centre bearing down a touch(washers dodgy i know but we had to try something).

This made a huge difference but still slightly there.

Got a proper centre bearing spacer ordered and some 5 degree wedges hopefully this'll tidy it all up.

My suspension bloke will be happy too, probably sick of seeing my face every week or so for the last 8 weeks. ( he is doing it all for original quoted price)

Hope this helps.

I hate that when shops(as most of you have experienced at a certain 3 letter major 4x4 store) say theres nothing they can do. I reckon if they do the lift they should iron out any problems that arise at no charge.

Just my 2 cents.
Dan
one more thing, its auto and shudder didn't change in 4x4 or when i changed from weekend cooper st's to blinged up highway tyres.

hey hiluxdan

who fixed your problem & where was it done
i went back to ARB this afternoon & they checked evrything & said that nothing can be done (except for putting the original springs back, what a joke)
ARB even phoned there suspension people & they said they have never heard that happening on a hilux before. So no spacer has been developed as it is not needed.
They heard of it happening on Patrols but not hilux's

I have no issues with this on my standard suspension diesel auto.

I'm close to approaching 40,000 kms but I do get a clunk noise when shifting from Neutral to D4 at times.

Regards

another question for you hiluxdan

im abit confused abit the wedge
to tilt the rear axle up do you insert the bigger side of the wedge towards the rear & the smaller side towards the front of the vehicle
hope ths question makes sense

by **hiluxdan** on Sun, 11 Nov 2007 10:43 +0000

Dave,
I'm on the Gold Coast and I'm booked in to get the spacer and bigger wedge put in on tuesday.
(It's a suspension shop not a 4x4 specialist)
Will let you know how it goes.
Can get the details to talk to him direct if you like. He said it's the first time he's had this happen on a lux so it's a bit of a trial run.

Bingo on the wedges, big end to the rear small to the front tilts the axle up.
Dan

dan
its strange that he has never experienced it on a hliux before
i also talked to a few guys at ARB & they have never seen it happen to a hilux either (dont know how true that is)
ARB said it used to happen on the older hilux's
So they put a wedge last friday from the older hilux's (same design)
Strange thing is that they put the wedge in back to front (Bigger end towards the front & smaller end towards the rear) which tilts the axle down.
Its strange but i think it has helped abit
Going tommorow back to ARB & they are going to change it around. Will see if it makes any difference
Still dont understand why they didnt tilt it up at the beginning

Hopefully by tilting the axle up & not down this will help the problem.

Mines not a huge lift, its only 40mm above standard & ARB are putting a 2 degree wedge in ( they said they dont have any bigger ones, again dont know how true that is)

Dan explain to me what the centre bearing spacer does, how will this help?

by **hiluxdan** on Mon, 12 Nov 2007 8:15 +0000

Dave,
No expert on the matter(learning by this experience)
but as far as I know the centre bearing spacer lowers the drive(front) end of the tail shaft slightly to reduce the angle to the rear diff/axle,
hope that makes sense
Dan
Sounds weird that arb tilted the axle/tail shaft connection down, like i say i'm no expert but that just doesn't make sense.

i just got old man emu lift kit put in at arb and my car is shaking on take off to!! has anybody solved this problem yet??? arb say that they have never heard of it before yeh right!

by **david allan** on Tue, 13 Nov 2007 4:00 +0000

matsake

What a joke hey.
exactly what ARB told me, never heard of it happening on a hilux, yeah right

tried putting in a 2 degree wedge to lift the axle, no difference at all.
Got them to take the wedge out & going to Toyota tommorow, will see what they say
