Here is an excellent instructional / pictorial, for checking and adjusting preload.

1ST--- This is not something to do for occasional mechanics --
If you're comfy with it,
IF you jack up your truck, grab the front tires @ 12 & 6 position, try & shake it off the mandatory jackstands, & feel vertical play, then your swivel brgs. are loose.
(tho' I think they could still be light on preload w/o play)
IF you feel play, remove (2) bottom bolts holding bottom swivel brg cap on offending side.
(Careful - Do NOT drop shims off of cap)
Remove thinnest shim & reinstall cap, drive it around & see if it solved the issue.
If not, replace shim & remove the next thicker one, etc.
THAT'S the concept - I've never had to do it, but it seems reasonable to me especially
given today's economic environment. It could take several tries.
I'd do it in a heartbeat, but I'd pop the tie rods for that wheel, remove wheel & then I'd set some preload to turn steering on that wheel.
You see it could be time consuming, the brits use a fishing scale to set preload so they don't test drive each time.
If you haven't already, I'd download the rave cd (shop manuals) & read them.
This is predicated on your sufficient mechanical abilities & I encourage Nobody to undertake repairs themselves if it's beyond their abilities.
luck,greg

you guys are awesome. I didn't realize that i could adjust the tension on the swivel *****. I'm comfortable doing anything and everything when it comes to working on vehicles, been a shade tree mechanic since before i could drive. I love disco's i just don't know them inside out yet. I have been through a 4.0 completely, i have it sitting ready to swap out my tired 4.0. I'm going to check the preload this weekend and see what i find.

Cool, I'll try (I'm one lazy man) to look up the preload drag on the spindle arm.
If memory serves, the (2)bolts @ bottom of swivel come out, pull swivel pin, the shims should drop with pin. (pay attention tho')
Mine's fine so I've not pulled them, I did however, repair gouged swivel ball & install new seal w/o removing from car --- cool
