Ok, looking through the FAQ's I couldn't see a top mount one, so thought I would make one. It's quite simple, but some may think it's a harder job than it is!
So, first things first, get all you tools ready!
You will need (obviously) a new top mount and a new bearing. The bolts on my car on the droplink, hub carrier and balljoint were all 16 or 17mm. The three top bolts (engine bay ones seen in first pic) are 13mm. The one in the middle of the mount needs to have an allen key placed in the middle to undo (I think the allen key is 8mm) and the actual nut is 20mm approx, not sure as I used old tools with whitworth measurements!
So here goes, you have all your tools right?
Jack up the car, take off the wheel and get some axle stands under there!
Before you do anything, I would recommend slacking of the bolt below a little as it'll make it easier than spending ages when the strut is off the car!
Only undo it 2 or 3 turns though!
Got a bit of 'Welly Finger' going on in that pic You may need to pop an allen key on the middle of the bolt to allow the nut to turn. I just used a screwdriver!
Next, you will need to undo three bolts. Firstly, undo the upper droplink nut, and the hub carrier pinch bolt where the bottom of the strut sits.
You can see thse bolts below, bit of a rubbish pic though. Please note, you can totally undo both these bolts but you may wat to leave the hub one in for a bit!
Next, you will need to jack up under the wishbone or balljoint a little, so that the top droplink bolt comes away from the strut easily.
After you have done this, then undo the pinch bolt at the bottom of the hub, and pull the balljoint out of the bottom of the hub.
This will allow you move the hub down further to relaease it from the strut.
With all the botls off, you will need to get the hub off the bottom of the strut. To do this, I used a fat chisel, and put it in the gap where the pinch bolt was at the bottom of the strut. Tap downwards slighty but not too hard. We want to gently move the hub down the strut and off the end without it falling down and pulling the driveshaft out!
After a while you'll be left with the hub floating and the strut just left hanging in the arch. Stick something under the hub to support it for the time being
Unbolt the three 13mm bolts as in pic one, and holding the bottom of the strut, slowly angle and lower it out of the arch.
