Cayman S Gearbox Mount Replacement

Today was the next saga in some bits of work on my Cayman.

After the change of engine mounts it was time to change the front transmission mount - it's a pretty pointless exercise changing one without the other being changed IMO.

There are a few well pictured tutorials kicking about - one good one is here:-

This is one frustrating and fiddly job to do!!.

I found that my old mount had a hidden Torx bolt on the part of the mount that bolts to the engine and the only way to get this is to remove the 2 bolts that hold the centre of the mount to the carrier. Not the easiest or most accessible job I have ever done on the car!. Strangely, replacement is less hassle (possibly due to having done every combination of contortion to get to this point!).

When everything was bolted up there was some real visible evidence of how goosed the old mount was. After changing the rearmost mounts tot he RS ones there seemed to be no visible evidence of this other than the new shiny bits, but now the front mount was in the tailpipes were a lot lower in the rear bumper aperture due to the front of the engine now not having any sag. A quick loosen of the clamp nuts and a bit of upwards rotation saw them back where they should be.

Test drive on Wednesday when I get a few other small jobs finished.

Rgds.

    UPDATE

    Did approx. 150 miles today to test out the recent work/additions so thought i would report back.

    Wow - what a difference this has made to the car - it feels a little more eager under the pedal which I suspect is the RSS under drive pulley, not huge difference but enough to feel a little more responsive. I have an alternator output check on my list of minor stuff to do and will report back if charging is an issue with the smaller pulley. I suspect all will be well as it was with the power steering but I will still have a check.

    The biggest improvement has been the new RS engine mounts and new front mount - car feels tighter, slicker gear changes and much easier to put into 1st gear. This is perhaps indicative of the state of the replaced items - I was slightly worried that there would be more noticeable vibration/harshness or noise with the RS mounts but the reality is there is slightly less and it feels so much more focused to drive.

    Very pleased with the results on these two items!.

    Chris - great info, thanks. I was wondering how many miles your car has done to warrant these mounts to wear out? My interest is that I wonder how mine are doing...
