No worries mate, I found out I could have saved myself £20 by just buying the bush part when I did mine.
Here's a how to I did on the gearbox mount which might help someone out as it tells you the sizes of all the nuts you will need tools for.
I spent a few hours on the car to change the rear gearbox mount, and a couple of other bits today.
I was hoping it might have been the cause of a knock I'm getting on shutdown so I don't have to change the engine mounts just yet, as they're £139.51 & £118.72 which after just laying out £400 on insurance I could do without.
The rear gearbox mount is only £40 and I've been planning on changing it since I did the front one so I thought I would take a punt on it first. It has improved it, and vastly improved the feel of gear changes, but the knock is still there so I'm going to have to bite the bullet on the engine mounts.
Anyway on to the job in hand which isn't hard at all
This is what the nice new one looks like
It's hidden away behind the rear under tray so that has to come off first, then you can see it sat sat in the gearbox support bracket.
Now it's time to prop the gearbox up with a block of wood on your jack so it doesn't slap you upside your head halfway through the next step.
The gearbox support bracket is removed by undoing the three 18mm bolts at either end. If you take note you can see where I've been laying frame.................
on speed bumps
Once these six bolts are out there are two 13mm bolts to undo on the mount. I forgot to take a picture at this point as I was in the zone, but I've circled them (poorly) in this picture.
Once they're out the bracket can be pulled down to pop it off of the mount, and slid backwards out of the way along the exhaust.
Once that's moved there are three 13mm bolts holding the mount to the box itself. Again I was in the zone and had removed two of them before taking the photo, but you can see where they were.
It was at this point the **** hit the fan and I began dropping f bombs as I realised I had ordered the wrong part.
Spot the difference
On closer inspection after I had calmed down I noticed the actual bushing was the same, it was just the mounting bracket that was different.
So out came the torx 45, and 16mm bits to pull them both to bits.
I then cleaned the old mounting bracket up with a wire brush before fitting the new bush to it. I had to use the bolt from the old unit as the new one was too long due to the slight difference in design.
There was quite a difference in the bushes just looking at them, but I could also feel a difference by hand when trying to move the gearbox once everything was back together.
Then it's just a case of working backwards to refit everything.
