Hi all Just back from a weekend road trip and the VikingWagen like a top until I heard an intermittent "knock, knock, knock" from the right rear undercarriage. The sound was at the same speed as the wheel rotation and it was more pronounced when turning slightly to the right. My first thought was that it was a bad CV. But I had just serviced all the CV only 3000 miles ago and the wear was very minimal. Maybe it's a bad wheel bearing. I've experienced that before on a Dodge Van, but the sound was more of a grindy "RRRRrrrrrRRRRrrrrr" rather than knocking noise. After about 45 minutes of driving, I stopped again to jack up the wheel. I gently put it into gear to spin the wheel and no noise. Then I grabbed the tire to check for free play and it was a bit sloppy. Hmmmm, bad wheel bearing or loose axel nut? Is it supposed to be that sloppy? A local mechanic put a impact wrench to it and was barely able to budge it, so I did torque it correctly when I last did the rear brake work. After arriving safely back home, I pulled the right rear CV axel and test drove with the decoupler engaged. No noise, but maybe that is due to the intermittent nature of the issue. At this point, I am leaning towards a bad CV because, even though serviced recently, I believe they may be the originals in the rear. At almost 150k miles, it's time they would fail, right? Maybe one of the cages cracked? What keeps me wondering is the Should I consider myself lucky that it did not fail after I drove it another 300 miles on mostly curvy steep coastal highway, about 10 miles of moderate off road, 1 mile of deep soft sand and forded one stream? Any thoughts or tests that would tell for sure which part is failing? Thanks in advance for any help! Keith O 1990 Syncro Westy |
