Hi

Well I didn't go for a lift kit-main reason is i want my truck to remain original,stock standard. new shocks, springs, tie rod end boot, centralised steering box, all suspension bushes checked, Tyres balanced again etc, king pin bearings,wheel bearings and everything else checked and all is good---

BUT I still get up to around 98 k's and it goes again. I am ready to cry. So disappointed i still have this problem. The steering wheel shakes from side to side --its like holding onto a vibrator and then the whole cab seems to shake also. So new suspension, new steering damper, new tyres, wheel alignment and everything else I've mentioned and its still there.
What to do next is beyond me. The only thing i can think of is it is in the steering itself. Might be something worn out that is causing it to vibrate like it does. Funny thing is it is not constant - rather intermittent and if i speed up then slow down it seems to help it. Well so much for the suspension idea--looks like its back to the drawing board and round 2 coming up.

Everything you describe was the symptoms of my car - my steering shake came on suddenly and was severe.
You mention the king pin bearings.
Did they just check them?
How did they check them - just a manual inspection looking in the plates from above and below?, Or just wiggled the wheel and said it was ok?
Did they replace them?
If they just checked them and then reassembled did they put the original shims back in or leave them out?

In my case, after i checked everything head to toe, including balancing, alignment and bushes, i then took the shims off the top and bottom of the kingpin plates, and the vibration was gone.
It tightened up the play.

If the original shims are still there, and they left the original kingpin bearings in place, i would remove the shims and then test.
Nothing hurt by doing this, you can always put them back.

If you don't know what im referring too have a look at this video on youtube and watch it until they get to the shims part.
In the video the refer to it as the swivel hub bearing shims

Hi Mrs H just wondering how things are progressing

Hi
I haven't done anymore to the truck this week. Actually have been waiting all week for mick (Mechanic) to call me back after I let them know as soon as I got home there was no improvement to things after a new suspension etc but no contact from him. Seems its take my money and run there. Not happy at all with the customer Service .

This is what my gut is telling me--new king pin bearings and shims. Rather them replaced than taken out. I know it won't hurt anything to remove them but would feel better having them there. Everything on my Truck is original from new so its understandable that things wear so I feel no harm in having them replaced along with the wheel bearings while I 'm going. At least I know myself then they are in good nick.
This is what I am getting done next so will let you know what the verdict is.

Lots of information on this on here. Unfortunately it could be may things..
A few little tricks to try.
Tighten wheel bearings and.go for a spin..
if no good try greasing each rod one by one and take it for a spin after each one.
The grease will short term pack any slop..
If it still wobbles try removing the shims on king pin bearings and go for a spin.
If it's still there replace the shims, and unfortunately that's the end of the free checks.
If you do all that and it still shakes I'd. Start with bushes.. Panhard rod bush is the most likely culprit.
And what makes it a right pita is if rear bushes are worn it can affect the wobbles to..

After one year of trying lots of things mine is now cured. It's a 2006 with around 185,000 when this started.
At 80 kph the shake was violent, felt like a seventies motorcycle having a tank slapper.

First was a new Panhard Rod. Then many wheel balances including on the car. Wheel alignment. Two new tyres on the front. Goodyear Wranglers, standard size. Only bought these because the spare was new one.

Then New Swivel Hub and wheel bearings. It still wobbled.

Every single bush in the front end replaced not at the same time and was trial and nothing had cured it. By this stage over $2,000 spent and it still wobbled.

Took the new front tyres off had that done maybe 10,000 km and they had worn so badly that he right hand one would not stand up. When rolled on the floor the tyres went in circles in opposing direction. So in effect they were fighting each other, probably caused by the worn parts.

Put the rear Bridgestone tyres on the front and it drives perfectly. A wheel aligner with a good reputation and Patrol owner claims its the tyres. He has found stiff side wall tyres work best.

So that was my journey and now very happy! If there are problems maybe try other tyres or check if they run across the work shop floor in a straight line.
