discomikey Posted September 11, 2014 Share Posted September 11, 2014 got in my truck for the short commute to work today and noticed that whenever i get upto about 30mph i have steering wobble. badly. not as if its out of balance, more like it is not round anymore, but egg shaped. anything below 30 is fine. and it certainly wasnt doing that when i parked it up last night. theres only 2 causes i can think that could have kicked it off. the tyre has suddenly overnight either got a flat spot or a bubble type thing, (unlikely, theyre 1.5-2yr old Goodyear Wranglers) or someone has been ever so kind as to have hit my truck last night and buggered off. (which i doubt as there are no marks) i tried to watch the front wheel whilst driving(feels to me like front drivers side) but cant see anything wrong, and checked for wheelbearing and swivel play and all is fine there so it really is a mystery. I havent jacked it up but im 90% sure theres no play as i really went for it rocking the tyres. dont have a spare tyre to test wether its the tyre either (i know what a tool!) any thoughts?

landroversforever Posted September 11, 2014 Share Posted September 11, 2014 Haven't hit a big pothole and damaged a tyre? Have you checked for any egg bulges in the sidewall? Quote Link to comment Share on other sites More sharing options...
MuddyWinny Posted September 11, 2014 Share Posted September 11, 2014 I guess it is unlikely but have you lost a balance weight? You can sometimes see the mark where it would have been. Quote Link to comment Share on other sites More sharing options...
Tanuki Posted September 11, 2014 Share Posted September 11, 2014 Could be a CV joint breaking up : is the vibration better/worse if you drive in a tight circle? As others have said, could be a delaminating tyre. Swap wheels/tyres front to rear and see if that makes any difference? Quote Link to comment Share on other sites More sharing options...
Ruurd Posted September 11, 2014 Share Posted September 11, 2014 Could also be the driveshafts... How much play on the CV joints there? Needed to replace them once and before doing so made the steering very wobbly. Quote Link to comment Share on other sites More sharing options...
Team Idris Posted September 11, 2014 Share Posted September 11, 2014 If it's an overnight thing I guess broken cords is likely? Quote Link to comment Share on other sites More sharing options...

discomikey Posted September 11, 2014 Author Share Posted September 11, 2014 would be CV's if i had got my orse into gear and put some shafts in the front. there is no front prop, shafts or CV's at the moment so pretty safe to assume its not driveline. it does really feel like tyres. although its intermittant and it happens at different speeds. you can power through it and it feels fine then but its always between 25-40, undulations in the road seem to provoke it if it isnt already happening and the wheelbearings arent loose, neither is the swivel from what i can tell. like i said i really went for it with the wheels on the ground notmally you can tell like that at least if theres some play although cant pinpoint it to either wheelbearing or swivel. not hit any potholes its not a vibration its more of an "oscillation" you can definately feel its the front drivers side. ive just been under it and checked all the bolts, which are all tight, wheelnuts are tight, ive rolled the truck along whilst feeling the tyres all individually, none of them seem out of round at all, no bulges in the sidewalls or anything like that. just plain wierd! anyone in COV with a 335/85 or 7.50 tyre (and jack and 27mm socket) that i could borrow for 15 mins to see if it is the tyre? what are the chances that a tyre that is so relatively new and a quality brand that can go wrong, and why, if it is the tyre, is it not constant but direcrtly related to road speed? surely if a tyre is egg shaped it would be egg shaped at 1mph and 100mph, not just 30-40???

FridgeFreezer Posted September 11, 2014 Share Posted September 11, 2014 Any loose steering components, joints, arms, kingpins... shaft in steering relay hasn't broken? Play in anything at the front? Quote Link to comment Share on other sites More sharing options...
discomikey Posted September 11, 2014 Author Share Posted September 11, 2014 nope, the instant you move the steering wheel the wheels also move, no play whatsoever.. "What? on a series? you must be wrong!?!?" Quote Link to comment Share on other sites More sharing options...
Cynic-al Posted September 11, 2014 Share Posted September 11, 2014 I thought all series vibrated, rattled and wandered all over the road? Spring or shock? Wheel damaged or lost weight? A good balancer should show it? Or got something stuck in or on a wheel? Prop shaft / uj? You say the steering components are tight but have you checked against the figures in the manual or just waggled at the wheels? Quote Link to comment Share on other sites More sharing options...
ejparrott Posted September 11, 2014 Share Posted September 11, 2014 Sounds very like my 109 you know, can't explain why it would happen overnight but the cure for mine was to take the swivel pin preload right up to top limit, even now it still twitches a bit.

Daan Posted September 11, 2014 Share Posted September 11, 2014 maybe check the tow? if it tows out it can do what you discribe. Also, does it have a steering damper? Quote Link to comment Share on other sites More sharing options...
discomikey Posted September 11, 2014 Author Share Posted September 11, 2014 alignment is fine, plus that wouldnt change overnight haha. and again, how would a swivel loosen up oernight? obvoiusly these are thing i will check as a matter of course when i get to the workshop tomorrow, but its still a mystery as far as i can see.

dirtydiesel Posted September 11, 2014 Share Posted September 11, 2014 30mph wobble in my experience is either bent wheel or badly out of shape tyre. Quote Link to comment Share on other sites More sharing options...

Bowie69 Posted September 12, 2014 Share Posted September 12, 2014 Loose wheel nuts? This was my thought, but wheel bearing checked apparently. Quote Link to comment Share on other sites More sharing options...
discomikey Posted September 13, 2014 Author Share Posted September 13, 2014 was the wheel, somehow overnight it has been bent, no scuffs on the truck really confusing. all sorted now as i had a spare modular, back on the road Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted September 13, 2014 Share Posted September 13, 2014 Could you have possibly of bent it at the end of your journey and not noticed as you were goingless than 30mph? Quote Link to comment Share on other sites More sharing options...
