Sorry I meant to add I would think a truck tyre place should be able to balance wheels but I've no experience about it with my truck I'm afraid. Good luck.

They do all sorts for lorries to racing and you can discuss your needs with them.
Good luck

Just noticed these guys are in St. Neots which is not too far from where I "grew up" (debatable term).

I am down there quite often visiting my mother, so can call in next time to get an idea of prices if that helps?

Hi Neil
I have talked it through with a few people and think my rear prop shaft is the culprit, the truck is taking a poor second place to a house extension at the moment.....I haven't even washed her yet!!!!!
I have had a few goes at the inside but am still finding Sahara sand in every nook and cranny.
I believe it can take a year to get rid of it all.

You have answered the problem without realising.
The fact you have refered to the truck as " She" means that wobbly moments are to be expected . They usually pass quite quickly so worry not, all is normal.

Hi lads a little update on this one, I have fitted new, stronger rear shocks and managed to get out in the truck for the first time this morning. I got up to 100k and the "wobble" vibration has all but disappeared. This is a result but I wonder if I still have a propshaft balance issue and that is what caused the rear shocks to fail or did I just have 13 year old knackered shocks? What do you think.

As in my last post the “ wobble” has got better but is still there. In the back of my mind I wondered if I had two odd weighted drums across the same axle that were setting up a vibration at a particular speed. The drums are coming off this week to check the break pads. Would it be bad form to swap n/s front and o/s rear drums? I have swapped tyres around on many vehicles but never drums, is there a reason not to?

Are they swappable.

My fronts and rears are different.

Brake shoes and Brake drums bed into each other. If you can swap them then I would imagine that the braking will be poor until they have 're bedded into each other.

I'd agree with Neil, front and rear are unlikely to be the same, and I wouldn't swap them without changing shoes.
I would - check all bushes and steering joints for movement.
Check the driveshaft joints - have they been greased?
You could mark a stud on each hub and re-fit the drum 180* from the original.
Check tyre pressures are the same across both axles.
Give up :P
Hope this helps,

For completeness I'd also take a good look at the transfer box and gearbox mounts for movement.

Well guys we serviced the truck on Wednesday and turned the hubs a quarter turn right and the wheels a quarter turn left. I have driven to Scotland today and the wobble is significantly improved again. I don't know if now I am just being too fussy. It was obviously a balance problem somewhere and the stronger shocks were holding it at bay. What would you do next? Or would you live with it.
