Knocking noise posible suspension issue?

[Jezza-7]

Trying to solve a knocking noise coming from the car which is making the engine shudder. If im decelerating then ever soo slightly accelerate i hear this knock. Definalty not the engine mounts as they were all replaced then my engine was rebuilt but my tca's were replaced about 1 year 6 months ago and they weren't g40 ones, yoof tutted when fitting the stage 3 frame lol. The top mounts were changed last month with vw ones and still got this knocking. Feels like the wheels are moving back and forth moving the engine via the driveshafts. Im thinking it could be TCA's are shagged.

Any suggestions?

Planning to change all top mounts and suspension in feb/march but trying to solve this 1st.

All bolts on the subframe still nice and tight? I had something similar when the offside subframe arm was loose - the nut and bolt on the 'elbow' of the arm where it meets the TCA needed tightening and all was well. If I grabbed the offside wheel with the car on the ground, and turned the wheel back/forth it would shift a little and knock.

I still get another knocking when going over bumps with the car in neutral or decelerating though which I need to check, but sounds a little like your symptoms also.

try your drive shaft nuts, they might be slack. i have had this happen on a couple of vw's
