Judder when driving 60mph-80mph in steering

**wantredtop** · by **wantredtop** » Mon Jul 31, 2006 11:15 am

Am i right in thinking it could be the wheels - i.e balancing, the thing is, i had them balanced a while go and it is still doing it? the wheels came with the car when i bought it, 15"s, the rest of the car is mint...could it be they are just sh1te alloys?

Any ideas?

Alloys could be buckled, they probably would have mentioned that when they were balanced though. Check the condition of the tyres for bulges/dents ect on the inside edge. Are they aftermarket wheels? If so check they have the correct spiggot rings to size them up for your hub so they are on central. Do the tyres wear iregularly, get your tracking done. [img]/smile.gif[/img]

honestly.... the tryes are wearing fine, the wheels have no kerb marks on them so they cant be buckeled..... i have not notice any bulges etc on the tryes, i will have another look. The wheels are aftermarket, i can check the sprigot rings to see if they are right, it is just really annoying me!

non-drivetrain issues:

1. wheels not balanced right
2. bent rims
3. flatspots on tires or tires gone eggshaped
4. warped discs
5. something could be wrong with the wheel bearing or housing - hardly probable.

drivetrain issues
1. inner CV joint(s)
2. gearbox engine mount gone or needs tightening
3. either of shafts somehow gone out of balance - not probable.
4. something gone out of balance inside the gearbox/front differential - not probable.

front wheel balance issues cause the car and the steering wheel to vibrate, but the steering wheel strong tendency to turn in one direction and then another is obviously felt and distinguished from the general juddering sensation when holding the steering wheel.
front wheel balance issues usually start happening even before 60mph, something like 50mph is usually the peak.

rear wheels balance issues start usually a bit higher than front (60mph+) - they dont cause the steering wheel to move. they rather cause vibration throughout the car felt nicely through the seat and other parts.

drivetrain issues also vibrate/judder the entire car, mostly the front part. juddering is felt through the steering wheel, acceleartor pedal and mostly the lower front part of the chassis where the gearbox is mounted. also, pressing the clutch makes it go away.
drivetrain juddering also appears at 60mph.

warped discs issues is obvious as the vibrations increases greatly when applying brakes.

keep in mind - bent rims can balance out fine on the balancing machine, but they're still bent and will judder just the same.. just like tires with flatspots or tires that have gone eggshaped.

oh yeah, there is also "the spiggot ring issue", but i had mounted wheels without them a couple of times and didnt have any trouble. imo they are just to help mounting the wheels. most of them are crappy plastic one that are hardly a tight fit so I don't see how they can help much :/
it is worth a try though

wheels can be buckled, they dont need kerb marks. i've buckled a fair few with no kerb marks whatsoever. i guess i've hit potholes and they managed to bend the wheel as i run pretty thin tires.
it is easier to check on the inside rim because it usually gets bent there. if the outside rim is bent then the inside is VERY bent. this is sometimes not obvious until you put the rim on the balancing machin and spin it slowly against a fixed ruler or something.

Cheers mate, will have a look into this further, maybe if i borrow some other wheels to see if that solves it, then try and elimate it one by one, i have recently just done a cv joint on the front, the otherside seems fine though ... mmmmm

**BlackKnight** · by **BlackKnight** » Mon Jul 31, 2006 12:41 pm

yea, that's the simplest way of checking and preserving sanity, get some wheels off a car that doesnt judder [img]/smile.gif[/img]

i changed both of my INNER CV joints, they were both dead. i suspect if one dies, the juddering kills the other or something.
outer CV joints dont cause vibrations, just clicking/skipping when turning and eventually they fall apart, lol.

lol ill get their in the end, failing that ill go to scrappy and get some steelies or something, see if their is a difference. Just a very annoying problem! coz it is making me speed, if i go over 80mph it is not. i dont think the police will believe me or have it!! lol.

CHEERS PEEPS

it is worth a try though</div>I mounted a wheel without one when it broke in half, it caused a judder through the wheel, it depends on the size difference between the wheel and hub. You cannot rely on the studs pulling the wheel central with alloy wheels because of how soft they are.[img]/smile.gif[/img]

**BlackKnight** · by **BlackKnight** » Mon Jul 31, 2006 1:44 pm

it is advisable to always retighten studs on alloy wheels after like 50 miles though [img]/smile.gif[/img]

Tie rod ends, caused juddering on mine had them replaced/fixed dont really know what they did but it fixed it.

**BlackKnight** · by **BlackKnight** » Mon Jul 31, 2006 2:46 pm

cant see how tie rod ends would cause juddering, but im not that mechanicaly minded so i may be wrong [img]/smile.gif[/img]
tie rods dont rotate so they cant cause vibrations by themselves. balanced and correctly setup(geo) wheels should go straight and cause no vibrations even with completely broken tie rods so i dont quite get it.

anyway, EY, dont get wheels from a scrappy to try it out becaouse if there's still vibration you wont be sure if the wheels from the scrappy are also badly balanced or bent. best to get some of another VX that you're sure doesnt judder and preferably has factory rims(no spiggot rings needed). al VXs have the same center bore and PCD for the same stud number.

Check your tyre pressures. if they are too low or all different this can cause issues as well. so check these before indulging in difficult and expensive fixes.

the inner part of the wheel is the weakest and the rim maybe dented. can be done easily with alloys even just going over potholes.
