Nissan Patrol 4x4 (Africa)

Thanks for the sugestions, Cedric I must admit I have not checked anything on the rear and it might even come from there.

Also not sure if it was mentioned, its a pickup with leaf springs in the rear.

Then I may be onto something .... if the leaf pack has changed and dropped, it will be exacerbated as soon as a load sits in the load bin ....

Nah, sorry. More caster (as in if the rear springs have sagged) would tend to straighten it out. There is no such thing as "too much caster" in this respect.

If the rear is very tall, so that there is less caster than there should be, that might cause the wobble to keep going, but won't cause it either.

If something in the back end is loose, or if the axle is mis-aligned, that might have an effect. Has this vehicle been for a wheel alignment, and are all the factors within spec?

But I must say, if nothing is loose, my money is on play in the steering box or pitman arm...

The only other thing I can think of is if something (like the hub carrier) is bent. To check for that, Put the front on axle stands, take the wheels off, put a dial gauge on the brake disk and the drive flange (the surface the back of the rim sits on) and see if anything wobbles when you turn the wheel. But this would take a hell of a bump.

If you don't have access to a dial gauge, bring it around to my place?

Or possibly the front axle casing is bent. This would show up as incorrect caster on a wheel alignment check.

Hi manne. My Trol is op die oomblik by Graham hyt vrydag na hom gekyk en hy se die rubbers op die raduis arms het hard geraak agter en die op die anti sway bar. Hy gan hulle fix en dan gan ons weer vandaar af kyk wat gebeur. Baie dankie vir almal se idees en voorstelle as dit nou nir uitgesort is nie dan sal ek weer alles deurgan soos julle voorstel. Hou duim vas.

Gihan wat was die uitkoms na Graham sy magic wand geswaai het?

Shalom

Jules die chessie to arm rubbers was moeg nou reg

Hi all , I have had my wheel balancing and alignment done twice on the same day by two different places , at 75-80 km I get a serious steering wheel wobble that is only at the above speed above or under that speed no wobble . Its a 2014 3.0 pickup . Have done a 50mm lift with a caster correction kit the tyres have done no more than 2000km and balances fine , are there king pin shims that one can remove to tighten up the tension on the swivel balls , I know this is the fix for landrover . Also I have a brand new steering damper in . Any advice is welcome , thanks

There are shims, but if you remove too much you could crack the hub carrier.

First check that the wheel bearings are correctly tightened first, many get this wrong.

Yeah I agree, removing the shims is the last resort. Wheel berarings need to be checked and torqued to the correct spec first off. Then the rubber bushes all round the front and rear suspension could be worn out and have just too much play on them. You may not feel it by wiggling things around, but this would be the second step I would take to fix the problem. Lastly I would remove one shim from both top and bottom swivel hub on both sides and make sure the hubs aren't too tight to swivel left and right. if ok, go for a drive and see if it is fixed. if it is fixed or better, then its time for new swivel bearings. Remember to put the shims back when you replace the bearings.

Just following on from my earlier post.... once the bearings are replaced, the shims are only there to get the load set up ( Nm ) of the bearings to spec. So in some instances one may find that with the new bearing the shim is not needed to get the correct preload tension.
