Hi All,

My 06 1.3 is on 60k miles now and I have noticed a slight knocking noise from the driver side when going over speed bumps etc. You can only hear it when the drivers window is open.

When I bought the car it had jus had a new wishbone on the passenger side and tracking was miles out, I have had the tracking done some months back however the front drivers tyre is bare on the inside, I don't want to have a new one put on if the wishbone is knocking the tracking out and it's going to be eaten up in a few thousand miles.

Any ideas?
 
The shocks seem okay, not broken but are original.

Anyway of testing the droplinks and wishbone to see if they are ruined
 
Can they cause uneven tyre wear? If so how easy are they to replace, would anyone be able to give me a little guide and a list of tools needed?

Would it be worth replacing the offside wishbone, the near side one was changed a few months back, not sure if they are an item that would be best replaced in pairs.

Thanks

Cameron

The rubber bushes - if original are now at least 10 years old,
that's what failed on our 1.1 at @10 years old,
with a wheel brace on the wheel bolts.. you could make the car wheel go back + forth in the wheelarch.. LOTS of free play:eek:

the car is going back on the road tomorrow.., so we will see how it has fared after it's 8 months "rest"..

Just grasp the drop link in your hand and try to shake it up and down. If it is badly worn, you will be able to feel some free movement and probably hear a clicking noise.
 
Worn droplinks are common and give a knocking, especially over speed bumps. They will not cause tyre wear.
Any uneven tyre wear that occurred before the wishbone was replaced will not be 'fixed'. The tyre will always be more worn on one edge, so as it now wears evenly, the edge that suffered more wear will wear out first. So the wear you see may not have a cause now.
 
I had a similar knocking on mine also only on speed bumps it was a badly worn track rod end so check immediately
 
Drop links are the first suspects, as has been said. Not easy to check while they are in place, and you will find that trying to move them by hand will not give a proper indication of their condition. Easy to remove and replace - probably a half-hour will see each side done. While there, change out the roll bar bushes - one each side. Easy but a bit fiddly. There's more than one style of bush, so make sure you get the right ones.

Check track rod ends for wear also - second possible culprit. You can do this with the car on jacks by gripping each front wheel and 'swivelling' from side to side while your mate feels for play at the track rod end knuckle.

If that doesn't cure your knocking noise, you need to start looking at suspension components, but the above two items are the fast wearing ones.
 
If there are two of you one rocks the steering wheel while one clasps the track rod near the wheel with your hand you will feel it
If by your self it's easier if you jack one wheel at a time with steering lock on try and move wheel from side to side ,

Worn track rod ends will cause excess free play in the steering. Try turning the steering wheel alternately right & left with the ignition off - any free play should be readily apparent. More than 1/2" (13mm) free play, measured at the steering wheel rim, will lead to MOT failure.
