knock from front suspension

[kris_tdi]

Just test driven a 52 reg tdi 130 sport.
There is a knocking noise coming from both sides (i think) front suspension. The wishbone bushes have recently been replace. Both springs are still intact. Any ideas?
Is this noise normal?

 

[kris_tdi]

its alright, found a post bout the same thing.

 

[rashcupra]

have you sorted your problem out chap?

i have the same problem..a knock from front passager side? bushes are ok?
Any ideas?

 

[rashcupra]

when does it knock turning speed bumps????????

 

[osorabjee]

yeah mainly over bumps or if there is a lumpy gear change at lower speeds(mainly 1st-2nd gear).
I have had the car on a ramp and had a quick look at the suspension boot which apears to be fine.
What do you recon?

engine or gearbox mount ???

 

[rashcupra]

as nath warr said could be the rear engine mount!
is it a clang noise or a rub noise or a knock noise or a grind noise??????

 

[Johnsey]

Tie rod end or ARB bushes would be my guess.

 

[osorabjee]

will have to get her back on a ramp and take a look. the sound is more of a cross between a knock and a rub but only at lower speeds? has anyone else had a similar issue?

 

[rashcupra]

arb bushes maybe,1 of the four 13mm bolts are loose or the lower arm bushes

 

[osorabjee]

where is that located in conjuction with the passenger side wheel? I greased the wisbone bushes up the other day thinking it may be them but both are sound?
Also with the 130pd engine what is the recomended time period of gearbox oil change? if its not a sealed unit?
Cheers.

the arb bolts either side to the droplinks the four 13mm bolts 2 either side hold the arb steady

I had a noise like this on my MK4. With all my mods i'd ruled out top bearing and mounts, ARB bushes and wishbone bushes, as these are now all new. Ive aslso had the TCA bushes changed. Well the noise was still there especially on the RHD side on full lock. Ive now since put new hubs/bearing carriers as part of my brake upgrade and the noise had gone. Im now thinking that the noise was coming from the lower ball joints that connects the bearing carriers to the wishbone.

mines creaking a fair bit changed droplinks but loking at this area i think the droplink will always foul with the wheel arch linning. but there are loads of things that it could be

 

[kris_tdi]

not had a chance to look yet as only picked up car yesterday. will report back at wkend.

 

[kris_tdi]

Right, found the problem.

There is a plastic collar that goes between the ARB and the bush. On both sides this has fallen to bits, allowing the antiroll bar to move about (wondered why the back came out quite a lot).
Will order 2 new bushes and collars and hopefully that will solve it

 

[kris_tdi]

oh btw it didnt make the noise when cornering, just on bumps in a straight line.

glad to hearyouve pin pointed the problem very easy to change them

 

[kris_tdi]

do you know if the plastic collars have a slit down them to replace? mine were in a million pieces so difficult to say.
