Suspension: Rear Subframe Bush Replacement

[AidXC90]

Hello XC90 owners,
I've bought a pair of rear subframe front mounting bushes (Part no. 30645393 or new number 30666697). These are the main bushes which connect the subframe to the body of the car. Volvo say these two front bushes are cracked. My 2005 model UK spec D5 AWD car has done about 130 000 miles.
The Haynes Manual describes how to remove the subframe - it's a big job - but not how to remove and replace the bushes.
I don't want to drop the rear subframe and I believe/ hope it is possible to replace these bushes without dropping/removing the rear subframe..
Am I right in thinking that? If that is the case, is anyone on this forum able to assist and describe the procedure and what tools are required?

Thanking you all in advance.

Aidan

I think the hardest part will be removing the old bushings. If they are anything like the front subframe bushings they are very difficult to get out. Basically you have to burn/hack them out. Like This:

Are there inserts available (like for the front subframe) instead?

Hi Greg and thanks for the video link. From that it looks like a very tiresome job and I hope I can do it with only jack ramps and anxle stands. I may have to get inventive

From what I can tell, there are no inserts available for the rear bushes but I may be wrong. Since I have new bushes, I'll install them anyway. If insertsfor rear bushes turn up later, that can probably only be of benefit as all I hear about the front inserts is that they make a noticeable improvement to handling.

Thanks again,

Of course there is a Volvo special tool, but a universal bearing/hub puller might do the job if you can get it onto the part.

Hi Greg,
Thanks for the idea. I suspect something like this set (https://www.amazon.co.uk/dp/B0796SPX...detail_3?psc=1) might be better to remove the bushing as it's seems to be, from what I can tell, a dedicated bearing/bushing removal tool with arms that can reach inside the bush and then be forced outwards to grip and pull the bushing as you tighten the thread.
Another thought I had after watching the YouTube link you sent was that removing the bushing might possibly not be not too bad if I use a hole saw to cut out the centre of the bush to aid collapsing the rest of the bush from the outside in.
But I'm not sure how to press the new bushing into place with the subframe still on the car. Might a trolley jack be sufficient to press a greased bushing up into place?

Regards
Aidan

A slide hammer system will extract but not insert. The system I suggested, with its forcing screw, can be used to press in the new part.

Good luck, let us know how you get on.

Thanks Oragex,
However, I think I prefer the method used by the guy further down in the post that you linked to (Burnout8488)
I think a screwdriver and hammer to remove the old one, and an 18mm socket to install the new one are more my style at this time
But thank you very much for your post. At least it shows me that some people have managed to do the job without specialist equipment.

Cheers
Aidan
