Rday Posted July 7, 2011 Report Share Posted July 7, 2011 While I have seen several more recent threads here and at SS about Collar & Angle Gear issues, and keeping in mind this is my first post, I have not been able to determine if this very comprehensive analysis by AlexD was completed, and what if any conclusions were reached. My interest is born of just noticing ominous clanging/clunking sounds that correlate to loading/unloading drivetrain cycles in the collar/angle gear area of my 2007 V70R MT. In theory, it should have the nitride fix, but after 70K driveline sensitive, but spirited [mostly highway] miles, I may have a failed nitride collar gear for someone to evaluate if that is of interest. In addition, is there a pattern to roughly how long after the noise appears before angle gear damage occurs, and are there any more robust collar gears now available, or is 31256008 still the best available alternative? Finally, did the discussions about approaching Volvo regarding premature failures on reasonably driven vehicles take place, and/or have they been willing to entertain helping some out of warranty victims?Thanks in advance for any information you are able to share!Rday Link to comment Share on other sites More sharing options...
Thombowlin Posted September 18, 2011 Report Share Posted September 18, 2011 This is my first post and am convinced I am talking to the right people after reading most of the info on the collar gear problems. You guys "R" awesome and are providing a fantastic service , thank you. I have a 2004 V70 R six speed manual. Love the car until lately . I have been without AWD for many months. Only found this out after my first trip to the snow. My problems have continued. Following a Passenger side axle replacement because of a bad CV boot, my test drive went bad with moderate throttle application . I heard a mild clunk.... Sounded as though it just popped out of gear, but I lost all drive capabilities . Towed the car home , jacked it back up for inspection and all appeared fine . The axle replacement went together great. If the collar gear is only related to the drive for the rear wheels it must not be my only problem. When rotating the front wheels they sound and feel very smooth. Normally I remember while rotating one side the other side would move in the opposite direction , that no longer happens. Any suggestions ? Link to comment Share on other sites More sharing options...
flyfishing31568908306 Posted September 19, 2011 Report Share Posted September 19, 2011 the AWD could be as simple as a fuse in the rear DIff. i lost my AWD and that fixed it. I got lucky.if you've heard the dreaded clunk, you're probably in for a bigger head ache.How did you know the CV was shot. The R's replace wheel bearings faster than my kids did diapers.Have you noitced a small drip center of car about where the dash would be on the floor?OH and welcome.I'm Mike.

Thombowlin Posted September 19, 2011 Report Share Posted September 19, 2011 Thank you .. Nice to get so much info in one place. Is the fuse in the fuse box. I'll check that . I replaced the axle assembly because the boot was bad. I got the boot kit but when I got the axle out the carrier bearing didn't feel right so I just ordered the assembly. I also replaced the hub so the whole side would b new. My main concern is the front axles have no drive.. In any gear. I do have a small leak from the right axle seal and another small one from the front diff. What components are bathed from the engine oil and what has it's own fluid. Thanks for the response . Am I correct in my thinking that the collar sleeve and the bevel gear both of which help drive the rear wheels , has nothing to do with driving the front axles ?

flyfishing31568908306 Posted September 19, 2011 Report Share Posted September 19, 2011 no, its a weird fuse thing in the diff.can't hurt to check for fuses everywhere either.i've read where the BG has a weep hole and will have drip when messed up. thats why i asked. as far as i know the BG and Collar only affect the rear. I could be way off though. Hopefully Josh will see this.If the front axles have no drive, how are you moving? Link to comment Share on other sites More sharing options...
Thombowlin Posted September 19, 2011 Report Share Posted September 19, 2011 I'm not.... It was on my test drive after replacing the right axle that I heard the clunk and lost all drive . Towed it home from just down the street. My AWD has been out a little while but the car has continued to run great . I now am back on jacks in the garage. The clunk was after a minor load on a test drive. I don't drive the car hard, but I do love the performance. ThomI'm not....

flyfishing31568908306 Posted September 21, 2011 Report Share Posted September 21, 2011 i'm curious what you find, keep us in the loop. Link to comment Share on other sites More sharing options...
Ihatespeedbumps Posted September 25, 2011 Report Share Posted September 25, 2011 I would make sure the new axle was installed all the way in the trans. The AWD models can get a bit of rusty buildup which may prohibit the axle from seating properly inside the trans. Typically dip the end of the axle in ATF to facilitate installation. Have you removed the axle to see if anything looks unusual? The collar gear does not affect the front wheels at all. BTW...

Thombowlin Posted October 10, 2011 Report Share Posted October 10, 2011 It was the wrong axle for my R. It fit in just enough to engage and drive down the street . But under moderate load stripped the 1/8 inch that was engaged. Having tossed my old one, (I know ... I'm an idiot ! ) I am now trying to find another one. Not as easy to find as I thought. Without the ability to rebuild the old axle assembly I am stuck. Any help would be great, thx. Thom ( the idiot ) Link to comment Share on other sites More sharing options...
BR05S60R Posted August 17, 2013 Report Share Posted August 17, 2013 Hey all, hopefully I can bring this thread back to life as I believe i am now experiencing collar issues. i did the test today of lifting one wheel (i did front left, im not sure if it matters which wheel is off the ground) and started to rotate it forward, keeping my eye on the driveshaft going to the haldex. initially it started to loosely rotate like it was skipping teeth but then it stopped and the tire rotated smoothly, with no noise coming from the angle gear or where the collar is located (which i found particularly unusual). i then found black sludge coming from where the angle gear meets the transmission, maybe the sludge is what initially cause the collar to engage the shaft and cause the driveshaft to spin?? anyway im about 95% sure that the collar is my issue. has there been any new developments in new collar replacements? is the one with the coating still my best option? custom made? btw i heard the clunk about a week ago turning right, on wet pavement, up and incline, into 45 mph traffic.....full throttle and experienced bad torque steer. 05 s60r 104000 miles. no replacement of the angle gear or collar to my knowledge but i am the third owner. any input would be awesome guys Link to comment Share on other sites More sharing options...
JRL Posted August 17, 2013 Report Share Posted August 17, 2013 Newer collars ARE harder Link to comment Share on other sites More sharing options...
BR05S60R Posted August 23, 2013 Report Share Posted August 23, 2013 Newer collars ARE harder when was the last time you had to replace yours? it has been a while since somebody has posted on here so i was just trying to figure out if, not only the newer ones are harder, but if they fixed the fit issues with the splines to the collar. i was under the impression that this is another major reason why they notoriously wear down over time.

rbbugbitme Posted February 20, 2015 Report Share Posted February 20, 2015 As a follow up, thanks to the info in this thread I went ahead and made a stronger collar that has been working great for over 20,000 miles so far. I sold a bunch of them too with no failures or other issues over the past year. Link to comment Share on other sites More sharing options...
lookforjoe Posted June 23, 2015 Report Share Posted June 23, 2015 Looking forward to seeing how the stronger collar sold by Ryan (PdVmotorsports) holds up in my 500AWHP wagon, with a new bevel gear also ordered Link to comment Share on other sites More sharing options...
