Hi all,
I was camping down south by the Murry and did a little 4wd looking for fire wood and the 4b was great until we hooked up the van to go home ,its a dirt track leaving Carters Beach and a light dirt road but I pressed the button on the dash to disengage the 4wd and carry on driving, I got up around 70kmph when this crazy steering shake began to happen and the car just shook so I pulled up made sure I was out of 4wd and even reversed back about 20 mtrs ,I did hear a click and thought oh well maybe it didn't disengage properly and continued to the next biggish town called Cobram and as we approached the town it happened again, we had to have the 4B, caravan ,family and Dog towed home to SYD and I just dove the car around the block again this morning and it didn't do it until I pressed the 4wd button again and I was able to make it do it again at 70kmph so I turned off the button but it still shook, I'm not sure if its an electronic fault or if something is broken in the transfer case hence the reason I'm posting this epic post LOL! any advice would REALLY be appreciated folks!

Regards
John.

Sorry forgot the most important part. We had a shake similar to what you are talking about and it was the left hand CV joint.

My advise is to take it to a Toyota dealer or a 4WD specialist, I could give you 5 or 6 different scenarios that cause this to happen and still not give you the right one, given that there are several reasons this may happen I would just take it to a specialist and get it checked out properly.

This may sound dumb but did you do some mud driving or on tracks that were pretty wet. I've had it where I had a lot of clay/mud build up on the inside of the wheels and it made the car shake like buggery. Cleaned off the mud/clay and all was good again.

Hope it's a simple fix like mine.

Cheers

First thing id do is ensure a wheel wasn't nearly off

John,

I'd be surprised if it's a transfer case issue if you have severe wheel wobble/shake.

70 clicks is about the speed where wheel balance problems make their presence known, so I'd suggest it may be something like Phil or Duncan mentioned. How long since you replaced the steering damper?

Once had severe wheel wobble in an HJ60, and it was the drag link joints that needed tightening up, but don't think your model has them?

You wouldn't have bent the front drive shaft, when you were looking for firewood?

Hope it's not an expensive fix,

Bob.

Hi all,
it is not Mud as I washed the entire car in Cobram and I don't think its a bent shaft, I checked the tyres for egging or a internal belt has let go, it just strange that it didn't do it this morning at any speed until I teased it by pressing the button then all the same symptoms came back,I was hoping a dampener was the fix but a bloke told me today that it wouldn't do this in a straight line at 70 ks and I do remember reading about this if you didn't disengage and I can hear the solenoid clicking out but it feels like something mechanical is staying engaged??

A steering dampener will do this at 70 kph been there done that, it could be uni joints, wheel bearings, wheel balance, cv shaft, separated tyres, you get my point.

Yep Thanks Phil,
I just find it strange that nothing happens until I press the 4B button on the dash?
I'm going to have someone look at it hopefully tomorrow or Wednesday and once I get to the bottom of it I will post on here, I've found that people on here have very good experience and sometimes could be specialist hence the reason I'm asking advice.

John.

Johnny boy,
I had a similar symptom in my 80 series which obviously has a beam front axle. The bolt at the lower end of the panhard rod fell out without warning and the whole front end shook like crazy. It was midnight and I was doing about 70 as that was the speed limit. I did not notice it was gone until after I drove the last 5 kms home at about 20kph.
If yous is a 105 series I would look under the front to check it is still there. If it is IFS then I look forward to hearing the answer.
Good luck.

I just spoke to a fellow that explained it could be a small motor on top of the transfer case which rotates and engages the 4wd that is causing the problem and that its a simple fix, I'm hoping that it is as simple as this, fingers crossed.

John,

While the servo motor may be playing up, and not disengaging 4wd when required, this doesn't explain the severe symptoms you described with the steering.

Activating 4wd is merely accentuating the symptom, and making it more pronounced. Power steering does mask many minor steering faults, until they become so bad that only a fix/repair can cure all.

A visual test you can do on steering joints, is park the wagon, with one front wheel turned, and hard up against a solid post, or kerb, and have someone turn steering wheel back & forth, while you eyeball all the ball joints. Any badly worn will stand like the proverbial.

How many k's has the wagon done?

Bob.

Hi Bob,
I will try that but myself and 3 mechanic mates have looked at the ball joints and front in general and can see nothing wrong ,I will try this just to eliminate the possibility of this being the cause, are you familiar with this motor on top of the Transfer case because I've been told that this is the exact symptom I will get if it is faulty but I'm still not sure how it works?

Regards
John.

John,

You haven't stated exactly what model 100 series you have, but as you pressed a "4wd button" it's not the poverty pack model. So if it's a GXL then it would be full time 4wd, and the button you are pressing would be for the centre diff lock? Am sure the use of CDL is restricted to certain speed.......can't remember:-)

If this is correct, it might explain your steering dramas?

Bob.

ps We had an 80 series GXL, and only ever used the CDL is wet & muddy conditions.......and it was often difficult to disengage due to lack of use too.
