I noticed that when lifting off (like shifting), there was a lot of movement / play in the engine / gearbox. So when I inspected the upper engine mount, I found the root cause rather quickly. The rubber deteriorated and there wasn’t much left of the original rubber bushing.
Having read the other options, like fitting a polybush, I went with the SuperPro version which looked like a good bit of kit. Mounting the new polyurethane kit was quite a breeze. Fortunately, the original bushing has a plastic ring 🙂 The SuperPro kit consists of 2 pieces, which makes the mount very easy to replace.
Result: a much better shifting car, putting the power down goes a lot better now. I will also replace the bottom gearbox mount with a polyurethane version soon.
Very easy job to do at home. This also applies to the S60 and V70, as these are quite identical.
Broken upper engine mount…
