Hi from MANLY NSW Australia
hey guys
Its so good there is a forum for this great little 4x4. its a rare car so im sure i can get some good info here as well as help people out.
So far things i have fixed on my car are the 4x4 flashing lights
the stuck horn ( removal of airbag)
and
getting rid of highway wobble
if anyone wants help with this im more than happy to give it to you
Cheers
Sal
hey again bud. stuck horn is
hey again bud.
stuck horn is a common problem in mitsubishi.
basically the switch fused together and was always on. had to take out the airbag to get to the switch and unstick it. then taped it up so it works again and put it all together again. there is a good video pon youtube of a guy doing this that helped.
i was convinced the problem with the wobbling was to do with my suspension. when i was driving at high speeds if i hit a bump or jinked my car to the left it would rock back and fourth till it worked itself out.
my mechanic ( great bloke) told me it was not my suspension and had to do with my tyres side walls being not strong enough. he pumped the tyres up to 40 and the problem was significantly better. Try that out.
if you imagin your tyres are full of water if it is only half full the car will wobble on top of the tryes, if they are full the there is not as much movement. he said when i do a tyre change to make sure i get tyres with stronger side walls etc. saved me $500 in shocks.
Northan beaches rocks.
speak to you soon mate

ahh yes, the slower speed
ahh yes, the slower speed wobbles, I got that when moving back to Melbourne when i had the car loaded up to the MAX, I wished I had adjustable shock damping to try fix it, But good point on the tires, that may have been adding to the problem, I never get this with the car empty or with normal loads including a couple of hang gliders on the roof, But on this trip it would happen even in a straight line on smooth roads, the wind on the wrong angle was enough to set it off, the worst was on left hand bends. It got so bad at times I thought it would go completely out of control if i didn't back off. Accelerating also helped stop it. Kinda foolish really. But i made it back safe and sound.
My currant problem is the hi speed (wheel RPM) wobble in the steering wheel, The car still drives fine.
The problem you are talking about is one Bob Oz, on this site, was talking about with his 3door also, apparently its more of a problem with the shorter wheel base of the 3 doors.
I have some adjustable damping shocks with my coilovers, I want to load it up the the MAX again and see if I can tune that oscillation out that way.
It should cause problems
It should cause problems regardless of load if that were the case?
Rack and pinion tight, in fact everythings still tight, only 113ks old when i got it. from a babying female owner by the looks of the logbook. But I will go through and check everything when I put new wheel bearings in soon.
wobbles
I get this when on long corners at highway speed with a bump, the car will sway and wobble for about 2 secs until I either steer out of the wobble or it calms down.
I've tried the hard tyres but it just makes the wobble happen at higher speeds, I was going to try new shocks and gie that a go, then try the sway bar links in the front. may well just be a poorly designed front suspension geometry.
is your's a SWB as mine is too, might be a SWB thing
hi BOB oz yea mine is a SWB
hi BOB oz yea mine is a SWB 2.0 lt. I thought it was poor design as well but surely we would have heard more about it if this was the case. Im due for new tyres so my mechanic wants to drop a size in width to harden up the side walls. he is old school so i trust him. he said that the SWB mixed with the tyres has a big impact on this. if you get out of the car and push on your tow bar so that the car is going side to side horizontaly you can actually see how much the car rolls on the tyres.
i thought it was my shocks too. i pulled them out and showed him and he says its definetly not them. ( he could have slogged me for shocks right there and then if he wanted to)
so in a couple of months once we have put new tyres on i will let you know.
p.s he says that now days cos all the tyres are such low profile this problem is rare and that not many people know how to diagnose it.
also mr BOB oz if you could help me out. do you have a keyless entry remote?? if so what are your codes.
cheers bud
I think its more likely to be
I think its more likely to be a dynamic problem, I have read a few books on Chassis engineering and handling/tuning to help me setup my race car.
Just like springs, the Tyre spring rates must be calculated in also, The taller the sidewalls are, the lower the resonant frequency, and larger the side wall deflection will be (generally ) It could be that when the resonant frequency of the tyres match the resonant frequency of the springs and bumps on the road that it becomes a problem. It could also be the front and rear bump and roll steer settings joining in with the resonant frequency.
Anyone thats done skateboarding will understand speed wobbles, and they have nothing to do with side wall flex. I did a lot of downhill skateboarding and learnt to control them even on a short board at 70kph + But the pros use a different turning circle on the front and rear of the skateboard bu using a wedge under the trucks in order to stop speed wobbles.
For and aft wobbles have been a problem in some cars. this could exacerbate the side to side wobble also. For example, If you had a car with a 50/50 front and rear weight distribution and used the same spring rates in the front and rear, there is an exact speed that will cause a problem for a given wheel base.
For easy calculation, lets say the spring rates give a R/F of 5per second and you hit a bump while driving at 60kph (16.66 meters per second), this will be a problem if your wheel base is 3.332meters. (need to check books again to confirm its not 1/2 R/F) The rear wheels will hit the bump just as the front springs are compressing after hitting the bump, the rear springs will also just be recovering from there rebound (from last bump of the weight shift from the bump to the front) as they hit the bump, causing the rear to be thrown even higher, since roads are not normally perfectly flat, this situation will be exited to a maximum as long as driving at this speed, The front and rear will continue to get thrown higher and lower at this speed
Im pretty bad at explaining things, hope you understand what im getting at.
Ill get some of the greeks running 29s or more on there SWB iOs to jump on and give some feed back. they must have these problems also if its a tyre thing.

just to clarify my problem is
just to clarify
my problem is not felt through the steering wheel more so through tyres and suspension.
Today i loaded the back of my car with about 7 cases of beer. i went about 90km per hour and provoked my car into doing to wobbles. it came out of the wobble a bbit faster than if there was no weight over the wheels. My mechanic told me that this would be the case (putting whight in the rear).
I dunno just seems strange to me that the people who designed this system would allow this amount of danger at high speeds. Im glad other people are having the issues though i thought it was a possible bent chasis or what not.
i have been having this
i have been having this problem at aboput 100/110km the whole time ive owned mine. it is definately a suspension and/or tyre issue, as i recently had my wheels balanced, and whilst it has helped a little, i still get the wobbles at highway speeds. i am considering a new suspension option in the hope to erase the problem. but im unsure if that will fix or decrease it... im hoping a higher profile tyre with stronger sidewall might also help a bit
Hi Guys, It's been a whil
Hi Guys, It's been a whil since I have been online. but I too had this freeway wobbles. around 110. I fixed mine. Doesn't do it anymore. My fix was replacing the worn rear lower control arm bushes. Replaced upper control arm bushes as well. They were really worn. My dad also ownes a LWB Pajerio IO. same issue fixed. Hope this helps you guys.

Welcome mate!, I have just
Welcome mate!, I have just moved back to melbourne after a year in Newport, Love the northern beaches, Manly to palm beach is a great stretch! did a lot of hang gliding there.
Stuck horn sounds like a pain in the arse! what was the deal with that?
I also have the highway wobble, between 100 and 110, not to bad at either of those speeds tho,I assume its due to a weight having fallen off. One of the front wheels has no led weigts, the rest do. But I have read of wobble in the IOs, How did you fix it? Im going to stick the spare on the wheel I thought was the problem today, But IF that turns out not to be the problem im keen to know what is and how to fix it :).
