Hi all,

I've fitted my A048R semi slicks back on today, and with all the extra grip they give, I've run into a bit of an irritating issue, that said, I did have it once or twice on the other wheels.

If I launch pretty hard, I get a clunk from underneath my feet - 1 knock.. that's it. If I then brake really hard, I get 1 knock. If I set of gently, no knock. It's like something is moving forwards and backwards.

Also, if I launch hard, I get a knock, then brake gently with no knock and launch hard again I still have no knock.

I have vibratechnics pbushes, and powerflex front bushes in the wishbones along with nearly new top mounts, vibratechnics engine mounts and a welded up (and substantially stronger!) top engine mount along with brand new track rod ends and rose jointed drop links.

I'll get underneath and have a poke about tomorrow, but what do you reckon? A balljoint starting to go?

JP

my track car was like that, was nearside balljoint. thought it was wheelbearing at first. could also jam a chock behind the engine mounting and wedge inbetween the cradle, see if it's moving a bit, but i doubt it's that

Check subframe bolts are tight

Also do a tightness check on everything thats been replaced.

Check ARB is central too, mine was not and wishbone used to touch it as it moved up/down

i had exact same problem when i fitted my hard poly wishbone bushes, only did it at very low speed

and going from reverse to forward or when very lightly braking. i put my car up on a 4 post ramp

and got someone to drive it - couldnt see anything at all. after a couple of weeks the noise got worse

turned out to be a loose subframe!

Check the exhaust isnt just catching the subframe. Mine did this. Looked like it should clear but when the engine moved it hit. Worth a look for sure.

Another vote for down pipe on the subframe.

It was the lower arm front bolt needed nipping up
