P80 AWD Rear Suspension Bushings


Recommended Posts

Little update:

 

My spare rear suspension parts went from this:

To this:

Most of the parts were powder-coated black. I primered and painted the rear axles with a Rustoleum cast-iron color engine enamel. You'll see one side of one is already painted black as it was brand new whereas the other needed a little glass bead blasting. The toe bars I did in a BMW Mystic Blue Metallic as I had a rattle can of that leftover. I have all of the bushings and an extra set of rear spindles that are clean and painted.

 

At some point I'll have enough time to actually install this stuff. :)

I also took a couple of pictures to show the drain hole in the cover that the machine shop made on the spare rear differential:

You can also see that there is a tiny vent hole near the top of the cover similar to what the angle gears originally came with. Although probably overkill, there's no reason why you couldn't install the updated angle gear vent and filter there as well.

Thanks guys. No intention of buying new Öhlins. Aside from a unicorn maybe floating around somewhere I don't think that would be possible. The ones I have on there are just fine. I just recharged the reservoirs with nitrogen. They had lost some pressure over 10 years.

As for the rear axle boots. I didn't replace them - one axle is new and the boot on the other looks to be in great shape.

Here's some pics of the installed custom upper control arm bushings. I had three sets made, one for me, the other two for Will and Hussein. When all this is said and done we will be the only 3 V70Rs in the world with this type of system.

 

Specs: the bushings are milled using UHMW, which is a harder compound than Delrin. The sleeves are hardened steel.  Here's a few pics...

 

All four:

#2 installed (this one was a real PITA!):

Had to make this little guy in order to help "seat" bushing #2:

Here's the process, using sockets as spacers:

Very Nice, Nick.

 

I'm not in any such to drop my rear suspension, however that tool looks pretty essential to the job of replacing the bushing in question. I will contact you when I'm preparing to do mine, & see if it's available for rental :)

Beautiful work there Nick. While I was in Arizona I had the chance to have the bushings pressed into my spare subframe and the LCAs as I mentioned to you and also drilled the vent hole on the rear diff cover and installed the vent just like on my angle gear. I used the Volvo anaerobic sealant in both cases to seal the brass vent which seems to work like a charm.

 

Question - noticed you don't have the backing plates installed at the rear spindles. Are you just installing those once you've gotten the whole lump bolted up?

Big Will or anyone else this far on the subframe odyssey, a few questions;

1. did you end up having to leave the old bushing outer sleeves in place to use poly replacements/

2. if you had your subframe blasted, did you have to hone or polish the bushing bores or protect them during the cleaning process?

Thanks
