ok boys and girls anyone come across this when towing my mates i/w twin wheel car trailer it wanders all over the road, at any speed / all roads /loaded,unloaded, different tow vec/ie transit,disco,volvo est,peep carrier.

we have tryed diff waits on back. the same
checked tyres. ok
wheel aliment. ok
chassis. ok
maybe someone has had this?

it's gunner be suspension init?
 
Is the trailer custom made or factory made? I would check the wheel bearings. If its a custom job let me know as it could be a few things.
 
could be tyre side walls flexing... low pressure or knackered.
is the hitch height right so the trailer body is level?
 
When you say the chassis is ok, do you mean it looks ok or you've had it inspected?
Could it have taken a knock? could the axle have taken a knock? And did you get the tracking done properly or did you measure between the front and back of the wheel with a piece of wood etc?

Need more info really. If any of that is not checked properly and almost precisely your just going to chase your tail around.

If sounds like the chassis or axle has taken a knock and isnt quite true so is skipping slightly when its moving.

Just my 2 cents.
 
Wheel bearings are the initial favourite as people forget that they need a regular greasing, and without that the bearings have a tendency to sieze up and fall apart, and that results in each wheel wanting to go in whichever direction takes it's fancy!!

Jack it up and check the bearings first!!
 
if a twin wheel isnt perfectly level then it can weave badly, used to get it on my twin axle caravan until i fitted a double drop plate to the hitch

When he says "i/w twin wheel car trailer" i assume he means ifor williams trailer, so not a home made jobby.

Check for buckles in the wheels aswell, i had this once on a hired trailer and it was all over the shop.

Does it tow the same with another car?

And BGB you carnt adjust the tracking on a trailer like you can a car...hes probly looked at the wheels and thought yeh they look like there going straight!
 
thanks very much i will keep checking all suggestions when i get chance in garage. welding an old disco at the mo,slowly getting there ?
 
if its an ifor williams trailer check the ride height of the towing hitch on yer car it needs to be 17+1/2" to the top of the ball i had this with one of those a 20 foot flatbed twin axle

it also helped loads when i made sure all the tyres were exactly the same pressure also make sure all the wheels run free when brakes are off ( no rubbing noise when jacked up and turned ) also make sure all the brakes work evenly such as left brakes working and right brakes not this can also cause snaking

easy way to test the brakes balance is to jack up one side and apply the parking brake then use a torque wrench to find out how well the brakes are working on that side then set the torque rench to that pressure and do the same on the other side to see if it clicks at the same point if not theyre imbalanced and need adjusting to equalise the brakes ( damn site cheaper than getting a brake test done at quick**** or ATS-eurobastards )
 
is it an indespension type suspension ?? i.e. no springs/shock absorbers

if so one of the stubs could be getting a little loose in the axle and causing the wheel to flop around/bounce uncontrollably, this probably entails a complete axle replacement to cure, or if the trailing arm has been bent at sometime that will also bollox it

drawbar bent/cracked ??

i'm not familiar with ifor williams trailers but at the back of my house there's a company that deals with/maintain mobile washrooms, i regularly see them having to change drawbar sections and towing heads due to cracking/twisting, sometimes caused by bad loading/overloading and sometimes caused by the jockey wheel not having been lifted and locked up correctly

between the answers suggested here you might figure it out

just a tip...

next time you have a problem that you hope for help with it might be worth you writing in english rather than text speak and make sentences that are easily understandable to assist getting a helpful diagnosis
