    Hi all, once again more problems with the B7...

    Main thing is that I've noticed at speed 60-70mph the steering wheel shakes slightly and gets worse the faster I go, at first this was the tyres, two had developed bulges, I got them replaced and the tracking done too as it was out.

    The problem appeared again on a trip down to London, I had assumed it was the front brakes as they were worn, I replaced the front discs and pads about 100 miles ago. They were ******, however new discs/pads on fine and they're performing great.

    Now 100 miles later the car shakes again at 60mph? I'm lost as to what it is? The bolts are fine, I have the correct spigot rings, the new tyres were balanced correctly.

    Only thing to note was that this appeared on the mot as an advisory not too long ago: "Offside Front Play in steering rack inner joint(s)" however the garage said it shouldn't be an issue.

    Thanks a lot for any help.

    Was the hub face cleaned before new discs fitted ???
    I had a drive shaft go bad on my B7 last year same symptoms as wheels out of balance drive shaft changed and it cured it.
    Is the shake from the front or under your seat?? I’ve done centre bearing carrier on mine(Quattro)

    Not using spacers

    Also no, the hub wasn't cleaned.

    It does feel like the whole car is vibrating, but can be felt easily through steering wheel.

    Can you check run out on front discs with wheel off that’s what I’d be trying first little bit of rust on hub doesn’t seem much but over a 300mm disc it’s a lot I normally use a flat bar or file with emery cloth wrapped round it

    This could be a few things. Some things you can do visually and audibly. Look at the CV boots on the axle. Are any of them torn? Any grease coming out? Do you hear any clicking or knocking noises when you turn the wheel in either direction? Vibration is tire or wheel related most times but once you rule those out you can start looking at control arms and tie rods. Rotate the wheels, front to back and back to front to see if the vibration moves or feels different. If the sensation moves then its either the wheels or the tires. It's not inconceivable that the wheels were not balanced right or a weight might have fallen off of one of them.

    Just trying to give you some things to try before you start spending money.

    Haven't had a chance to have a look yet ,but I've noticed on my drive home just now. You can feel the vibration through the gearstick, and the brakes are smooth and responsive. I did some loops on full lock in a car park and I couldn't hear anything.

    you need to eliminate parts one at a time really, when it first started happening , what did you fix and did it work , if for only a short time then that wasn't the cause but more likely just masking another issue.....
    As you have already replaced the obvious parts then its very likely they were not to blame anyway, i'd be looking drive shafts , cv joints etc as the vibration is looking more a drive/transmission issue …..if you have looked at all thing steering and suspension wise.

    Thanks a lot for all your help guys,

    I'll start with looking at the drive-train, especially the drive shafts, I'll let you all know how I get on.

    Yeah, when the garage fitted the new tyres (after the bulges) they re balanced them, they're fairly reputable so it's unlikely they've balanced the wheels wrong.

    Hi all, bit late but I've finally managed to get a few hours to spend to have a look at this.

    Firstly all the tyres look fine, the wheels look straight and I can't see any cracks or signs of a buckle, it doesn't look like any weights have fallen off the wheels either.

    The brake discs look and feel absolutely fine, I checked all the lines for bulges and I couldn't see any, the only thing I can note is that the torx bolt that holds the discs in place is missing both sides.

    I also cleaned the face of the disc where the wheel sits as it looked grubby. I tried pulling on all the top arms and tie rods to feel for any play but they were all solid. I noticed that the drive shafts both moved in and out by about 2mm,i guess that's normal.

    I'm at a loss as to what to check for now.

    Any more help is much appreciated, thank you.

    Look up a video on YouTube on wheel bearing test. You’ll have to jack up the car but it requires you just pushing and pulling on the wheels. Could be helpful.
