Outer Limits 4x4 Board

They old disco runs very sweet and at times am loving the return to the dark side!

At speeds >80, if I hit a pothole etc I get front end death shakes.

I'm pretty confident it's not balance = it is smooth all the time otherwise

The front shocks seam good too

The front wheel bearings already replaced

The tyre bloke suggested an increased aftermarket steering dampner.

He reckons he's had a few Disco/Rangies with similar - any thoughts????

Check all your bushes - mine did the same and it was a shock mount bush.

Front end wobbles are always hard to pinpoint to one thing ... in fact they are usually a combination of things but mostly related to worn parts. Sounds like a combination of worn king pin bearings (check to see they are not RS, and are correctly tensioned .... remove any spacer/shims if needed) worn rubbers (radius arm and panhard rod) and maybe a worn steering damper.

As simo63 said check your swivel pre loads, this make a big difference to steering kickback as well as the damper- also check the panhard rod bush's.

well i just went through this same problem, have 35 simex that are not balanced and was getting bad shakes. replaced steering damper got a little better, replaces drag link and track rod and tie rod ends, got a little better, then took out the pahnard rod and replaced with polyurethane bushed, problem gone. tyres still not balanced. anyways go to pedders they have the poly bushes the standard ones will need to be pressed out but the pedders ones will drop right in.

and also fiddled with the swivel preloads that also helped

9 times out of 10 its the panhard bushes, this has been done to death but no one seems to search anymore

ohhhh......NASTY......

Well once the search is fully back up then all go !

Will replace the panard rod bushes with the poly ones, someone else suggested that and check Simos suggestions too.

Cheers everyone

yeah the poly ones work well in the panhard, easy to fit.
search is working fine

But only if you do not do any dusty work eg Simpson.
I did a set in 5kk . They had about 1MM gap between the centre sleeve and the bush.

IMHO if you do not have big tyres, metalistic bushes are better in the Panhard rod.

If your panhard rod bushes look OK then it will be the swivel bearings in each hub. On an old car it is a waste of time to just up the preload by removing shims as the bearings "brinnel" ie look like a corrugated road, with the low bits at straight ahead. new bearings required.

BTW there are two types of shimmy, parallel when the wheels stay in the same relationship, and wobble where they move in different directions. Parallel is Panhard. Wobble is tie rod ends, or swivels.
They feel different.

I've got the same issues with mine , I was just doing some research on swivel pins . I'm guessing you just do the top one ...Right ?. I found this which was helpfull.

And this one

I hope that helps .

I'm giving mine a go this weekend.

Sorry mate but Wrong. You do both top and bottom if you do any of them. When I've done them in the past it's usually the bottom one that is the most farked ... often pitted and rusted on the older girls.

Always do both and while you are there, make sure you replace all the seals etc. Read the manual, learn about the preload and do them right .. or pay someone else who can do them right for you is my advice.

I must be the 1 out of 10 cause when i had this problem with an 80 series it was the radius arm bushes.

I'd put ALL bushes at the top of the list followed by tierod/drag link ends, then bearings.

The bushes should be replaced always. they can look fine but they can still be knackered.

Thanks for that, after researching a a little more it was obvious I needed to do both.

Use super pro poly bushes in a rover forget all the other ones go with the super pro and a can of lanolin spray grease give em a squirt every month and they will out last the truck .

x2

Had the same problem two different occasions, one was shot castor/ radius arm bushes after lifting 2'' the death wobble showed, second time bent drag link causing severe wheel alignment, third time different car was castor bushes again.

I wouldnt use pollys at all. Stick with the rubber in my view. But yep most likely pan hard bushs. Have someone move the steer wheel side to side and watch the panhard as the front moves. You will see it plain as day.

Poly's are good for the panhard rod but i wont use them anywhere else either.

theres poly's and theres super pro poly's, the super pros are very good in comparison to normal poly's

Exactly my reason not to use them

Also check wheel bearings. They wont cause major issues, but I tightened mine up and it improved things a bit.

Huh, you won't use super pro poly's cause you have to oxy them out?
