Re-Discovery Posted July 25, 2007 Share Posted July 25, 2007 Well the journey to Billing and back was very interesting, which equated to approximately 7½ hours of white knuckle ride!?!?! It appears that I am suffering with a Violent Front Wheel Shake between 38 - 50 mph, it is fine below that speed and fine above that speed and only happens when the vehicle is under load i.e. Decelerating within that range is okay?!?!?! I am running 35x12.50x15 BFG Muds on Mach 5 Bead locking Rims within each tyre I have approximately 15ozs of Airsoft BB’s in order to balance them from the inside out (see this link http://4x4trailhunters.com/article.php?id=18 for more info) I have an amount of play in my front nearside CV Housing, but have been told that this shouldn’t cause any grief, but will be removing a shim or two shortly in order to hopefully resolve this issue!?!?!? : My Panhard Rod Bushes are fine!?!?! Any ideas as to what it could be would be gratefully received?!?!?! B) Quote Link to comment Share on other sites More sharing options...
Les Henson Posted July 25, 2007 Share Posted July 25, 2007 Normally if you can 'drive through' a wheel wobble it's the tracking or wheel balancing. Les. Quote Link to comment Share on other sites More sharing options...
Re-Discovery Posted July 25, 2007 Author Share Posted July 25, 2007 Normally if you can 'drive through' a wheel wobble it's the tracking or wheel balancing.Les. Thought about Wheel Balancing but that is not normally an issue until about 50mph and not the relatively low speeds I am experiencing it at?!?!?!

Pete Attryde Posted July 25, 2007 Share Posted July 25, 2007 Have you checked that there is not mud stuck to the inside of the rims, as this can cause this. HTH Pete. Quote Link to comment Share on other sites More sharing options...
nick8556 Posted July 25, 2007 Share Posted July 25, 2007 I had a mate with a similar problem to this and it was a damaged wheel ( buckled) that was causing the problem Hope this helps Nick Quote Link to comment Share on other sites More sharing options...
Øystein Posted July 26, 2007 Share Posted July 26, 2007 Play in any part of the front wheel/steering links may play a role. Check all links, PAS box drop arm, wheel bearings etc. Øystein Quote Link to comment Share on other sites More sharing options...

Re-Discovery Posted August 1, 2007 Author Share Posted August 1, 2007 Just thought I would post an update on what has been done to try and resolve the issue so far; Fitted brand new top and bottom bearings, shims, gaskets and top and bottom pins to both Swivel Housings!?!?! Fitted brand new track rod and drag links ends!?!?! Just had all four wheels aligned, and tracking done, camber and castor all okay!?!?! No play in any of the Prop UJ’s front or back!?!?! All Suspension bushes appear to be fine!?!?! The only thing that I haven’t yell checked as far as I can tell is the wheel balancing and the reason for that is that my 35’s would not fit on the tyre balancing machine at the tyre place that did my wheel alignment today.?!?!?!?

Escape Posted August 1, 2007 Share Posted August 1, 2007 Have you checked or replaced the Panhard rod and its bushings? If there's play, the axle will be able to move left to right, causing severe wobble. Have a mate shake the steering wheel violently while you watch the rod and bushes carefully. I had this problem on my 90, at first I could drive through it, but it got worse until I changed the bushings. Quote Link to comment Share on other sites More sharing options...
Re-Discovery Posted August 1, 2007 Author Share Posted August 1, 2007 All the bushes apear to be fine, my panhard rod is one of the Scorpion Racing Adjustable ones and therefore only has a bush at one end and a rose joint at the other!?!??

nickm Posted August 1, 2007 Share Posted August 1, 2007 All the bushes apear to be fine, my panhard rod is one of the Scorpion Racing Adjustable ones and therefore only has a bush at one end and a rose joint at the other!?!?? would still try n borrow a different set of wheels n tyres to try out Quote Link to comment Share on other sites More sharing options...
LR90 Posted August 1, 2007 Share Posted August 1, 2007 Agreed, you've stuck 15oz of BB inside those tyres and that doesn't sound like much. I've got more than that in lead on some of mine. Borrow some know good wheels Quote Link to comment Share on other sites More sharing options...
Escape Posted August 2, 2007 Share Posted August 2, 2007 All the bushes apear to be fine, my panhard rod is one of the Scorpion Racing Adjustable ones and therefore only has a bush at one end and a rose joint at the other!?!?? What a coincidence... So was mine! But there was considerable play in the rosejoint, so I forced it out and machined the head to take a Range Rover Panhard bush, handling has improved dramatically since! Easiest would be to try with a different set of tires first though. Quote Link to comment Share on other sites More sharing options...
dirtydiesel Posted August 2, 2007 Share Posted August 2, 2007 Mark, Have you looked at the caster angle. Your running about a 4" lift arn't you so it could be worth putting a angle guage on the swivle pins to give you an idea if the caster, it should be at or around +3 degrees. The other thing to look at is the condition/operation of the steering damper. Dan. Quote Link to comment Share on other sites More sharing options...
dollythelw Posted August 2, 2007 Share Posted August 2, 2007 look at the panhard rod mount on the axle and check to see its gone oval, if so weld a 3mm washer on Quote Link to comment Share on other sites More sharing options...

Re-Discovery Posted August 13, 2007 Author Share Posted August 13, 2007 I have just replaced the front Radius Arm to chassis bushes (with Polybush Oranges) as they had gone and were allowing forward and backwards movement of the axel?!?! Took it for a spin on Saturday and it didn’t appear to be doing it anymore, but when I took it for a spin yesterday it seemed to be doing it again!?!?! I can definitely say that on gentle acceleration it doesn’t appear to be doing it (or be that noticeable), but under heavy acceleration it really does get a shake on!?!?! I can assure everyone from speaking to several people who work in the tyre industry that it is not wheel balancing (due to the speed at which it comes in, being so slow, between 35-50mph) so please don’t post that. This week I will be swapping the front wheels with the back to see if one of my new front wheels are buckled somehow?!?!?! There is no play in any of my propshaft UJs!?!?! I am quickly running out of options on what it could be, please feel free to post any sensible suggestions?!?!?! Thank you in advance.

wizard Posted August 13, 2007 Share Posted August 13, 2007 Have a look at the swivel pin bearings and try and check the preload tension. I think its in the haynes manual somewhere. wizard Quote Link to comment Share on other sites More sharing options...

In that case people who work in the tyre industry are talking poppycock because on the last two sets of new tyres I have had I have had steering shake at about 45mph and in both cases it has been wheel balance! Not saying it is that but I am definitely saying: don't rule it out unless it has actually been checked! Quote Link to comment Share on other sites More sharing options...
jas97disco Posted February 8, 2008 Share Posted February 8, 2008 If you've a disco ,would think its the steering damper. I had the same wobble in my freelander at similar speed, replaced damper and problem went. Quote Link to comment Share on other sites More sharing options...
