Very much icing on the cake at this point. A shift boot made from pieces of and R seat. 

OK so, Had the rear seal replaced on the angle gear as well as the fluid changed out. No longer leaks on the hot exhaust making the terrible terrible stench. Started in on wrapping the exhaust and g

Alright I should see there return early next week but the kind people at Performance Shock Inc were gracious enough to provide me with some pictures of the rebuild and testing process.

If he was referring to the crush sleeve, it doesn't need to be replaced as long as you don't crush it more than it already is. Maintaining correct pinion preload is what is important, and you don't need a need crush sleeve to keep the preload within spec.

​I was referring to the collar. We had trouble with re-torquing rear diff pinions (at Volvo) when that wasn't replaced. That was back in the '90's however ;).

Since it''s the exact same part, I personally would change it. If you have had success re-using it & getting the correct preload, then perhaps it's not an issue in the AG application. However it is the same part number (meaning they didn't revise it in any way for the AG application).

minor update, Ohlins for the rear came back. took what 3-4 weeks to get fixed?

I altered them it was on its way as they said they would order in the hose from Sweden  ahead of time. I guess it didn't happen based on the turn around time. However the hose its very fresh and im confident is slightly larger then the one on the other side. 

Next is to get the rear springs working still. No luck on Ohlins springs and I have not yet restored to the 'euro R' springs. Would like the adjustable set from Ben but they are not available yet. 

Other wise the brakes and the updated tune fro Steve have been epic. The car shifts at a little bit higher rpm and just really screams. The occasion where I will actually gun it still takes me a bit by surprise. 

Also still in need of a STC switch so under hard braking the gearbox doesn't kick into neutral.

OK so,

Had the rear seal replaced on the angle gear as well as the fluid changed out. No longer leaks on the hot exhaust making the terrible terrible stench.

Started in on wrapping the exhaust and got a td04 turbo blanket. I still need to finish the bottom portion but it's looking like a winter activity. The cabin is noticeably cooler now and I've hopefully extended the service life of the front shocks and reservoirs. 



Rear Kaplhenke ( springs and perches are in place finally. Needed to get a shop for assistance as I didn't want to removed the lower arm supports on the ground. 

The items themselves are really nice and feel well made. 


Many minutes of brake bleeding afterwards (shop exploded the rear Brembo's cross over tube) everything was back together and no longer bottoming out. 

A slightly scary moment was putting the shock on the drivers side back in. The work being done bottomed out the shock so much so it didn't rebound and was 'crushed' to the minimum height, after removing the bottom bolts and pulling it open by hand it seems to be working normally. 

Started off with what I thought was pretty high up, moved from 9 to 12.5 'valleys' on the 325lb springs. 


9 here


12.5 here


Car handles better then before (as one would hope without the floppy rear end)

I have the Öhlins set to 4 of 8 in the front and back, the corner response and ride quality is excellent. 

Hoping to incorporate the delrin sub frame bushings in the next set of upgrades. 

Mechanic after affirming he bled the brakes properly (the second go around) said it drove really smooth and made no noises which was surprising. Again with a brand new suspension all around I'd hope for as much.

Acquired some Blue Coil 450lb springs thanks to Lookforjoe. 

Following Sam Millers / Ben Kaplans suggestions to just wind up the spring seat worked very well. Replacement only required removal of the rear Porsche calipers. Thankfully these are nice and eash to access 13mm bolts that aren't all frozen up like the oem fronts tend to be. 


I will probably pull the passenger side back out when I finally get a moment to replace the e-brake on the wagon. I'm in need of another bump stop as some how the driver side one escaped at some point in the cars life. You can also only get the buffer as a single piece. 


Pain in the butt to get the bump stops in and out. Best suggestion in a flat blade in the top to wedge the lip down a bit, exact opposite for the install. 
Camera Shifted after I removed the jack stand but it still shows the set down effectively.

I have new eBrake cables & all shoes, hardware removed from my wagon - if you need to change it all :)

I might take you up on that. I think I cut my dust shields properly based on your previous pictures (though they seem to be gone now and I did it from memory) but i will certainly need new cables for next year. 

Heavier springs have made all the difference and the car now has the correct rake to it. 

Compared to the V70 XC monster truck

You just need a single mass flywheel, came on every manual 850 produced. You can buy one for less than $50 from most any junkyard...

I thought so as well! But i'm looking to avoid potential mishaps with the altered crank sensor holes. This specific one comes from a 98 s/v70 naturally aspirated car. In babyclaudes thread he shows the difference between the two setups.

This has the all important square notches vs the round holes. 

$75 shipped was a fair offer (figure at least $25 to ship the thing)

      Our much beloved V70R (~110K miles) overheated on a family trip from Oakland to LA this week.  It now sits at a dealer/service station waiting either for us to pour more money into it than we can afford right now, or for you to come and pick it up.  Asking $1500, OBO.  Then you can either fix the thermostat (and possibly head gasket) yourself, or part it out.
      We are the original owners, with complete service records.  Right before this trip, it had a regular service and new front brakes done (but, ugh, not the thermostat).
      Needs to happen by Weds July 8, in Los Angeles. Paypal, Venmo works.

      Hi im new to this forum and this is my first post.
      i have a V70r 1999 
      there seems to be difficult to find a gearbox replacement 1208943. Reason for replacement is the gears are slipping when the atf is hot. I want to rebuild it but instead of taking down the one on the car I’m looking for one used I can rebuild and swap with the one on the car.
      my questions is: can i use other gearboxes F.ex 1208942 from xc70? 
      Does anybody here know What might be wrong with the one i have? No DTCs!
      Does anybody have A 1208943 they might wanna sell? Or maybe 8111193..
      other things I can do except flush as I just did that? 12l jws3309+treatments+leakstop
      where is the Volvo race mechanics ? 😅

      A slightly neglected but making a comeback, 70R that is just itching to find a motivated owner. Nearly every month, we all read, or hear about, another R selling for CRAZY money. This particular R is NOT crazy money. It's reasonable money. $4000.00 and who knows, it may be even cheaper. What I would REALLY be interested in, is a TRADE. STRAIGHT ACROSS. CAR FOR CAR. 
      MINE; 2005 VOLVO V70R ONE OF 674
      190,000. Mostly fwy commute miles silver paint with the typical Gobi colored leather. Yes, it would be nice if it were flash green with Atacama but it's not. Clean title, never been involved in any significant accidents. NO panel has been repainted. Has a few of the typical umps and bruises but nothing big. Interior is Gobi leather and is a little tired. CaR starts easily, idles nicely, revs like a pissed off banshee,  has a working 4C system, all three settings, NO CHECK ENGINE LITE, NO codes other than ignition ring and rear wiper motor. 
      Automatic trans with a new, Quality replacement, valve body including all eight shift solenoids. New, not ebay Chinese "reman" solenoids as well as all new proper transmission fluid. I have set adaptation thru VIDA only to find out that the VIN LOCKED TCU is probably "bricked" and needs a XEMODEX replacement.  APPROXIMATELY  $499.95  I just don't want to deal with it as I have other cars and projects in various stages of completion and have no room. 
      If I were to keep it, I would absolutely do an M66 Install as this conversion alone seems to make people go mad and throw huge amounts of cash at owners. 
      If I had the room I'd strip it bare and make it a 6 speed track only car with full cage etc.
      Yours; 95-97 855R  prefer red but any R color would work. Needs to be in reasonably decent condition. NO SALVAGED TITLE. Must run. NO more than 2 years out for tags. I understand how old they are and how crappie the interior plastic is now so I won't freak about a cracked or broken interior. PLEASE,  NO TOTAL POS CARS BUT SOME ISSUES ARE EXPECTED 
      Interested? Let me know what you're thinking and maybe we can make something happen
