Like a lot of people I’ve had trouble with replacing the front driveshafts. Put 2 new ones into my ‘91 Brumby and still had what sounded like clicking cvs. Eventually traced it to the journal/spline at the end of the aftermarket cv being about 3/4mm longer than the Subaru original. After the journal that the wheel bearings sit on there is a shoulder at the end of the spline, before the thread. On the aftermarket driveshafts (3/4mm longer)the hub butts up against the shoulder and this stops the crush effect needed to properly locate the cv end in the hub. It was only after looking closely at the aftermarket cvs and an original cv that I noticed the difference, also there were witness marks on the aftermarket cv journals that showed the bearing was spinning on the journal when it shouldn’t have moved. Rebuilt original driveshafts, problem solved. There’s lots of comments about aftermarket driveshafts being rubbish, I don’t think they are, I think you just need to make they are dimensionally correct in every way to the originals. I will have the aftermarket cvs machined to the correct dimensions and I think they’ll make fine spares in the future.

Hi, my ‘91 Brumby has a noise coming from the front end. It’s a thumping/clicking like a cv. Although no clicking on full lock turns left to right.Have put in two new driveshafts (protex) although one has been in for a couple of thousand kms, the other new this week. Have just replaced wheel bearings both sides. Axle nuts torqued to 196nm. Steering rack ends replaced this week. Have been chasing this problem for months, really can’t work it out. Could it be a worn hub surface? Or duff driveshaft? Any thoughts greatly appreciated.
