you put new oil in with the new strut. how does that mean its leaking. it only needs bout 100ml or so to take up the space

the aftermarket inserts are different to factory ones hence why there is oil in them from the factory. ive never felt a strut that had overheated. no idea where u pull that from. the aftermarket inserts that go in do not fit the exact shape of the strut and yes they can move a tiny bit at the bottom. this is why u add a bit of oil. fill it bout 3/4 of the way up the srtut. forgive me if it is not exactly 100ml but its not a lot of oil needed

I had the same setup noise etc. I thought the Shocks were tight but apparently they weren't so that seems to have fixed it. Hope that helps anyone having the same problem. I really thought they were tight but just over time they become loose and i guess its progressive so all of a sudden it is really loose.

Yea, i know what you're saying - but i have checked the gland nut and it seems really tight - i can't move it any direction. However i can't really tighten the nut with the proper tool without doing a bunch of pissing around... the whole - taking the strut out of the strut top/bearing plate, removing the radius rod, dropping the bottom arm and leaning the strut out from under the guard etc. This is because the tool slides over the top of the shock in order to get to the nut - refer the picture in my earlier post... quite an annoying design really! It's going into a Suspension specialist shop tomorrow - it is one of work's customers so they shouldn't charge me too much to track down what it is... I will update you when/if i find out it is. Cheers, Jason

87Calais, Sorry I should clarify what was tightened. First the gland nut, but only marginally. But forgive if this sounds tech, the shock sits in the strut tower thing and there is a twisty thing that is tightened at the top of the strut where you first see the shock coming out. That was tightened as well. (I think) Any ways noise is completely gone.

the oil is just to stop the inside of the pipe rusting as water will collect in there, just a bit in the bottom will do,old oil is ok,and the bottom of the shock has to be tight on the bottom, may need washers or packers to tighten up tight

sounded like a worn bush to me, probable lower control arm.

Hey all, Got the car back from the suspension shop today. Turns out it was the gland nut. As VLNA2T said it was tight but not tight enough. They also tightened the main strut nut (the one that sticks outs the centre of the strut tops) as it wasn't quite aligned properly and had worked a little loose. Had a chat with the guy at the suspension shop when i went to collect my car. He said although the nut would've felt tight, the insert would've moved around in the strut slightly and worn away a little and made itself enough room to move around and make a noise. He said he got a few various tools of the trade out and tightened her up good and proper. That seems to have fixed the problem! Yay - no expensive insert or strut top replacement!! THANKS EVERYONE for your help - now others can use this thread for info when they strike the same problem as it seems to be a reasonably common problem. Thanks again, Jason
