Also theres a hel of a lot of vibration between 70-80. I have recently had the car tracked and balanced and both came in fine. Theres no loose nuts of bolts that i've found hanging off. It sounds like it's coming from the middle of the shock. I've not changed yet is the top mount although i do have a set of TRD ones. 
..disconnect it and see if the knock goes. I went through this with my Tubby, changed almost everything(drop links, bushes, top mounts etc) and in the end I believe it was the shock itself. The noise was noticable when driving from cold and usually went away after a few miles .The suspension worked fine and MOT testers could never find any play anywhere.& manually lifting the hub I'm inclined to thinking it may be the insert. The noise is defiantly most noticeable around the centre of the shock. & may need to buy a new insert.andrew30044047 wrote:After taking off the wheel
It's a bit of pain as I just got 2 new TRD top mounts that were a bit expensive
It's not unusual for Bilsteins to get a bit noisy as they age. It sounds like the while front of the car is about to drop off. I'll have another play around tomorrow & see what else I can rule out being at fault. Still, new top mounts can't do any harm over the 19 yr old ones that at on the car. It turned out the ARB mounts where they bushes attach to the chassis ...... had corroded straight through. An hour at the welders and it was good as new. Replaced the drop links but that didn't cure it. After a little more research it turns out that the 19mm nut which mounts the strut to the topmount (under the black cover) had come loose by maybe 2/3s of a turn (fairly common, apparently). Tightened that up and the knocking disappeared.pacman wrote:I've had this exact problem recently.
The only problem was the description of which nut wasn't too good so i couldn't work out which one it was. I'll go get my big bar on it and see what happens.
