now somethign has been bothering me for a while, I get a slight knock noise from the rear left suspension when turning left if the road has a bump or is on an angle... now it doesnt do it all the time but it is there and its annoying cause I have no idea where its comming from...

any ideas on what to check?

Check the diff mount bush's ? see if they are split.

I agree, I got the luxury 19' on my FG same problem (only its right side). dealer said diff mount bushes were split, still have not got the changed though

I would be putting the superpro one in if I were you .

My car smashed all diff mount and centre bush's after 20,000 k's

I have superpro in now and all good.

Fitting all poly to the front has tightened up the chassis in mine immeasurably...and the noise increase is only marginal and still within acceptable limits. Well worth the trade off. Look forward to doing the rear.

Tyre life has also improved dramatically as the suspension now has a hope in hell of keeping the wheel alignment to spec under dynamic loads, although the rear is not bad at all in that respect. To fit rubber in the diff area with the loads it generates is a huge ask and can only lead to trouble. To have the poly bushes last the life of the car is an additional bonus.
