Tyre rubbing on standard disco

[beatmasterdave]

hi all,
ive got a standard disco, with 235/70 muds on. never rubbed before, but now, when im in full lock left, i realised some rubbing. checked underneath, and my near side tyre is rubbing the radius arm (i think its called) and making it all shiny. theres a lil scuff on the other side, but not major. has something had a knock, or just need adjusting?
cheers all!!!!!!!!!

You need to adjust your steering lock stops....., this will have an effect on your turning circle.

Dave,
If you look at the front of the swivle housing you'll see there is a large (19mm spanner size I think) bolt near the swivle filler cap. The bolt has a lock nut on it.
Jack one front wheel off the ground, clean up the threads on the bolt and release the locknut. Then turn the steering hard over until it stops, the head of the bolt will be nearly touching the axle case and the tyre on the other side will be touching the radius arm. Now you undo the bolt it is touching the axle case and keep winding until the tyre is clear of the radius arm. Turn the steering wheel back a bit and go to full lock again to check that the tyre is clear, tighen the locknut, then do the same on the other side.

Check the steering track rod (the one linking both swivels together) to see if it has been bent.

The steering stop on one side adjusts the position of the wheel relative to the radius arm on the other side. If the trak rod is bent then it will adjust the stop position allowing the tyre to catch.

Nowt but problems for u dave lol...

[extreme90]

if it didnt catch before but does now then id say its a problem with tracking
have you bent your trackrod ?

[beatmasterdave]

nearly brand new sumo track rod. (the front one :oops:  :( ) the one behind looks straight but might be a bit off after doing the front one a little while ago. i think i'll get a sumo to replace that one soon. havnt had a chance to check under there yet. great advice everyone!!! :D  :D cheers :D  :D  :D

Also a van might have been built with 205 tyres on.

[beatmasterdave]

it had 205/30s on when i got it, now its 235/30 mud terrains. its only recently though. also, when turning, its easy, then hard, then easy again etc. the power steering fluid is full.

If it's feeling "knotchy" as you turn the wheel then try putting a good load of 3-in-1 oil on the two steering shaft U/Js in the engine bay (the one that goes into the steering box.

If you've only recently changed to wider tyres and the steering stops weren't altered then you need to go through what I said above as the 235's are wider than the 205's and will hit the radius arms.

ive had these muds on for 10 months just started playing around this month :?

Well something has change in the steering if they weren't rubbing when you first put them on.

Get the tracking checked and also make sure there's no play in the panhard rod bushes, try to tighten the securing nuts as well, these could cause the axle to move from side to side.
Also, jack each of the front wheels off the ground and grab the tyre at the 12 & 6 o'clock positions and shake. If you feel any movement then get the swivle pin preload checked. If there is play here then someone looking at the seal around the chrome swivle will see it moving.
Then grab the tyre at the 3 & 9 o'clock position and shake. If you feel any movement here then check the wheel bearings.
Then look for cracking or movement in the chassis bushes for the radius arms.
 
If you've already checked the front drag-link & track rod then then one of the above should lead to the problem.
