problems with bevel gear removal V70-XC70 1998

One thing I forgot to mention in my first post is the problem I had with my bevel gear removed.

On my 1998 (it may be different on the newer cars) the firewall-side main engine mount found on the FWD models is not present. The bevel gear is attached to the transmission and rests on a 'ledge' with a rubber bump stop on top of it. In this way it sort of acts like an engine mount but obviously it's not as good as one of the real hydraulic mounts like the FWD has.

With the bevel gear removed, the radiator-side hydraulic main engine mount is taking up all the slack. Also I don't think the mounts are very good at withstanding 'pull' forces - ie: being pulled up as opposed to being pushed down on. The radiator-side mount received much more 'pull' forces with the bevel gear gone, and it received more stress in general with nothing there to hold the other side of the block steady.

Needless to say this ruined my radiator-side main engine mount. I think it took about 10 months or so.

When I replaced the bevel gear with my newly rebuilt unit, I replaced the engine mount with a URO mount from FCP. It seems well constructed and it feels good. I'll report back on it's service after I've had it a while.

To replace the radiator-side engine mount you pretty much need to remove the radiator fam + fan shroud. This was not too difficult but was time consuming.

Don't jack the engine up too much or you'll ruin the other mounts and/or drive axles.
