Found out that my trailing arms bushings were shot, so I changed them and put everything back together.
Went for a 10 min ride and about 3/4 of a mile from home I heard a "BOOM" coming from the passenger side....and almost no traction... Every time I try to move the car.... It will make a loud nice.... Long story short...Took the car home on a tow truck. Inspected the car and the passenger side inner CV joint retainer clip (cir-clip, the one that prevents the tripod come off the CV housing) was missing. No signals of it inside the boot. I did NOT remove the boot while changing the trailing arms bushings, but I might have forced a little the axles while removing the trailing arms that may could had help to misaligned the cir-clip. There were some metal shavings inside the boot. The loud noise was because the tripod was skipping over the tripod "cup" or CV joint housing... Question is.....Have this ever happen to you guys? I know that the use of tripod CV joints is the less common conversion here. Could this happen again even having the cir clip correctly installed. I put about 60 miles on this car before the trailing arm bushing installation and the car was driving pretty good with no problems or weird noises at all. Thanks in advance! Pictures for reference: |

Haven't had that happen and I've got 12K on the clock. Your axles and output flanges seem to line up well. When you installed the 1/2 shafts what was the clearance between the end of the output shaft and the body of the CV?

I'm not sure if this is the answer you are looking for, but I can move the axle all the way inside the cup and if I pull it, the bearing will come out like 1/4 (10mm) approx. I'm thinking that my axles are to short and may add an Inch to each one of them. Other thing that I could try is to make a 1 inch spacer between the outer stub axle and the cv joint. Thanks for your response!!! |

Thanks for your response!!! If your drive train is bolted in place and the outer CV and 1/2 shaft are bolted to the wheel there should be "just enough" clearance to slip the inner CV onto the trans stub. I wouldn't go anything greater than an 1/8". (IMG:style_emoticons/default/agree.gif) that your 1/2 shafts are too short. (IMG:style_emoticons/default/beerchug.gif) |

If you change out a stock Subaru axle in a Subaru, that's about the clearance you have once you've disconnected the ball joint from the control arm. So even that action on your instructions Kent is a little loose but since our suspensions in back don't turn (at least they're not supposed to!) that's just about right. I've changed two of them on my Impreza within the year - takes me about half an hour per axle. |
