hi all

can anyone please help.

my hdj80r has started to tram line,( sorry i hope this is the correct term), or is following changes in road contours. while braking it gets worse and is becoming very uncomfortable to drive.

the front hubs have been fully rebuilt, with new bearings etc

can any one steer me in the right direction as to what this could be.

thanks in advance

andy.

Andy,.
you say the hubs were rebuilt. If they were taken apart completely and ball joints removed and so on I would get the alignment checked. Also, check that the wheel bearings have no play in them. Check with the drive flange removed as it being in place can 'hide' play in the bearing.


My 2 cents!

Gday,
Have you recently changed the suspension?
Sounds a bit like castor adjustment.

Cheers

Agree fully if you have a 2 inch or more lift, most vehickes need offset caster bushes to bring it back in spec. Some don't though.

Undo one end of your steering damper and see if there is 1/2 inch of freeplay in it as this is also fairly common and will lead to tram tracking and uneven tyre wear.

G'day Andy

If the Cruiser is tram tracking, I would suggest the steering damper is at fault and possibly the tie rod ends.
You have most likely ~ concentrated the wear points ~ to these items,with the hub and bearing renewal.
Are your tyres by chance wide, with a relatively flat tread face, such as a Bridgestone Desert Dueler A/T ~ 50% or less tread life remaining ?
If this is close to the mark, replace the steering damper with a good quality Return to Centre unit. I had the pleasure of rebuilding the greasy bits on my 80 Series fairly recently too. ~ Image Could Not Be FoundImage Could Not Be Found

Had a similar problem with my Troopy after it was lifted 2" with caster bushes. Was pulling to the left, ie following the camber of the road. Knew all vehicle components were ok so figured wheel alignment related problem. Result was a camber bush fitted to the LHS hub and it was put back to normal. Recommend Axle Pro in Campbellfield for this kind of analysis and fix. A happy customer you might say. Have read that there are a heap of variables that can cause these problems,, even a simple change of tyre is enough to upset the steering characteristics of the vehicle. Cheers and good luck with solving your challenge.

I was driving a company Pathfinder recently with the same problem. It was bad at any kind of speed from about 90k/h up and was attrocious under brakes or on uneven surfaces.

I fixed it at the local servo in about 5 min. Pumped the tyres up, and set them at the recommended pressures.

I hope you have checked the simplest thing first.

thanks all for you're reply's

the 80 has a 2 inch ome lift which was on it when we purchased it, also only has 15x 31 inch atr coopers that are showing no sign of uneven ware.

the 80 has always steered great up until recently, noticing a slight wandering on the high way and more movement under braking.

a friend has told me that the bushes from the front diff and the control arms could be the culprit does any one have a view on this it would be greatly appreciated.

thanks all for you're reply's, i will certainly look at the above suggestions.

kind regards andy

That would be where the off set caster bushes go

Mine does the same - all the bushes are worn out - I think is is about $850 for a full Nolethane bush kit (including castor correction bushes) for a 2 inch lift. I'm too slack to have done it already - but it is getting to the stage that I will have to do it soon!!
