Steering Shake

Postby ufc1972 on Tue May 30, 2017 7:12 pm

Hi all.
Just wondering if anyone else has a similar problem.
I have a 2015 plate MQ Triton exceed. I have 17inch tuff t01 rims and 275 x 65 BFG At. I also have a ultimate suspension lift kit. TJM centre bearing drop bracket and tail shaft spacer. Since I have had the ute the steering has had a shake/wobble when driving at highway speeds. If the road is perfectly flat then it is fine but but on any road that is uneven or slightly bumpy then the steering wobbles and shakes from side to side. If you hold the wheel loosely its very obvious if you hold it tightly then its not really obvious to look at but you feel it still. To be honest it is driving me crazy. I love everything else about my ute but the steering problem is driving me crazy. I have had 2 wheel alignment, the wheels balanced and rotated but it is still the same. I have tried heaps of different tyre pressures from 30 to 40. 40 makes it slightly better. There is no mud on the inside of the rims. I have a 2010 Challenger with 205k on the clock with worn out tyres and suspension but its steering feels like a limo compared to my ute. Obviously the wider tyres and rims will make the problem feel worse but still there is a problem there.
Does any one have any ideas on what the problem might be or does anyone else have the same issue. I have read online about a steering rack problem in the Pajero sport causing this same problem but the forum is in another language and does not translate to English well. PLEASE HELP :(

If a wheel alignment and balance hasn't solved the problem and you don't have a bent wheel I would be looking for a good front-end specialist. Sadly, the only other causes I can think of would be expensive ones.

What are the expensive causes that you are think of.

Also I forgot to add the I have a 45lt water tank under the back of the ute (right behind the spare) and when this is full the steering wobble is a little bit worse. I have a ironman rear step/tow bar to. Maybe the weight right at the very back and no weight at the front mixed with wider rims and tyres is magnifying a problem.

Chuck the challenger wheels on it and see if it still wobbles

Sorry to ramble but also when I am coming up to a stop sign and have to slow down quickly over uneven ground the steering wheel moves from side to side a bit like the feeling of a 4wd with a worn out steering damper.

Am getting new tyres fitted to the challenger in the next week or so and was planning on getting the tyre shop to first put the challenger wheels on the ute. So at least I will be able to cross that off the list.

If anyone here on the forum lives in Hervey bay and owns a MQ triton I would love for them to take mine for a quick drive to see how they think it feels to their ute.

I'd lift the front wheels and give them a spin by hand and see if both run true.

If the wheels wobble, then take the wheel off and do the same with just the hubs and see that they run true.

What often seems to get overlooked is contaminants stuck between the disc & hub or wheel & disc faces.

Faulty discs or wheel bearings may be possibilities.

Hopefully it gets sorted soon, nothing more frustrating than issues like this.

Do new rims come with hub centric rings? Sometimes aftermarket rims require them. Double check the centre bore is a perfect fit. If this is the issue you can buy machined aluminium rings that fit between wheel center bore and mounting centre bore.

Good luck.

Thanks for the advise.

The rims did come with hub centric rings. (well I was told them did)
I will check the disc & hub this weekend.

I actually worked out today that the weight that I have at the back of the ute looks to be the main cause. When I empty the water tank it reduces the symptoms by around 30%. I think that the ironman rear step/tow bar and the water tank right at the back of the ute is taking weight off the front and seems to highlight the problem. Also the MQ triton kerb mass is 45 kg less then the previous model which I am guessing in mainly due to the all alloy motor so the front end is a little lighter but the front coils from Ultimate are the same (to the best of my knowledge) as the MN Triton, so maybe the front suspension is just a little to stiff when you consider that I have 80-90 kg right at the back of the ute. Tonight I loaded up about 90kg of weight in the front footwells, dropped the water from the tank and when I drove the ute it was a fair bit better again. Not perfect but a good 75% better then it was.. Don't get me wrong the problem is still there but getting some weight up front gives a massive improvement. So I told the mrs that I need to get a bull bar fitted and some nice heavy duty side steps. Yes I know it sounds crazy but for whatever reason the weight up front really did help. Maybe the wheels/tyres combined with the lift and weight at the back of the ute just show up a weakness in my ute. Once I get the bull bar fitted I will see how it is and go from there.

Maybe the dog-dick they fit on the rear diffs actually should go on the front one. :ugeek:

Your weight adjustments are demonstrating that a real problem exists and you can control a dampening effect.

Well, usually, a side to side wobble on the steering wheel means misalignment. if you have had this checked out and the problem is still there it suggests that, somehow, the wheels cannot be aligned which suggests that either you have run out of adjustment or something like a bent axle or other structural damage is causing the problem.

This happened to me years ago with a Ford Cortina. The front suspension was apparently a bit light on structurally and had sagged so that the alignment could no longer be adjusted correctly. A bit of welding and reinforcement solved the problem.

Hi,
I have a 2007 ML with low km - 113 000km, and currently having the same problem.
I thought about it and left me with 2 things...
Front coils not sufficient
Steering rack problem.
I have thought to do a mod on the steering column, to fit a rubber coupling to absorb the vibration.

So i will be fitting a ironman bar and winch and see if this weight at the front will help.

Condition of springs, shocks and load only affect how a problem is masked.

To get vibrations, wobble, etc, something has to be out of round, out of balance or misaligned.

If any of these are in effect, the tyres will get uneven wear patterns and only amplify the issue.

Simplest place to start is jack up a wheel and spin it to see that its running true, including that the tread is running level (not showing a high or low spot) on some side or patch.

Hi, I have been chasing a similar problem ( not sure if it is the same as yours) which has been driving me crazy. I have even gone to fair trading, but they are no real help.
I will share my experience, but it may not help you. What I have found, and this sounds weird, is a few things. There is something wrong with the engine/gearbox mounting in the car. If you hop under the car and push the rear of the transfer case ( at the tail shaft) up and down quickly, you can get the whole motor to get itself into a flap which will creates a funny shake through the whole car and feels like a steering or suspension issue.
The things I have done which help are turn my TJM centre bearing lowering bracket upside down, so that the angle between the transfer case and the first part of the tail shaft is only about 1/2 degree, and then make the angle between the first part and the second part of the tail shaft exactly the same as the the angle between the second part of the tail shaft and the pinion angle. I did this with caster wedges. This will also get rid of your vibration on take off and helps a lot in getting rid of what you are feeling. I have now bought another set of engine mounts that I am going to apply a poly urethane I bought from america specially to stiffen them up. I am just not sure what negative effects this will have. I have also been told ( by the mitsubishi tech guy from melbourne) that if you have a bull bar, that putting on the side steps with brush bars, can help. But I believe that fixes a symptom of the problem rather than the problem itself. These are just my thoughts and experiences, hope they can help.

After I did a 50mm lift I had so many wobbles & shakes from the front and rear of my MN I didn't know where to start. The steering was doing what you described as well, it was bloody terrible.
So, I tried wedges, weight changes, Tail shaft spacers, gear box & engine mount changes, Turning the tail shaft center carrier bearing & wheel alignments etc.
Now, I did I end up getting these wobbles & shakes down to an acceptable minimum, but I could never get them to completely disappear..
That is until I put a straight single piece tail shaft in it. Soon as i did that she was back to normal with not one wobble or vibration from the steering or transmission. It's the best thing I ever did.

I have had the straight tail shaft for over 12 months now & I have had both rear wheels off the ground at the same time in the scrub a few times & it has never touched the cross-member, Although I have had the cross member modified slightly to give an extra 25mm clearance, but IMO it was unnecessary.
EDIT: Might pay to check the welds on your rear axle housing spring seats as well. We thought my MN chassis was bent left to right (not up & down) because the rear was way out of alignment with the front & no one could get it aligned true. It turned out that the weld on the left hand rear spring seat was not done correctly at the factory. It was positioned incorrectly and out by 10mm, it was also bent downward at the front. How it got through factory inspection like that defies belief because it would have been near impossible getting that rear spring on there. Although it did not make the MN wobble or shake, but while you were driving it just felt like the rear end was trying to overtake the front end.
