Evening everyone. I'm a long time lurker of these forums and they've been great in finding common issues on my previous Octavia vRS and a Fabia Scout. I now have a 2015 Scout and am having trouble finding info on a problem that's been developing for some time.
Mine is a 2.0 diesel 150bhp, manual. It's got 98,000 very well maintained miles on the clock. Several months ago, a bearing noise started at the rear of the car. I changed from my summer tyres to winter tyres and it stayed the same. I ended up replacing both wheel bearings but haven't made a difference. I'm now in the territory of a propshaft bearing or rear differential. I was just wondering if anyone knows if this is a relatively common problem. More recently, the noise has changed where it's very noticable while decelerating while off throttle in gear. The noise almost completely disappears when accelerating. I think I found one post on these forums with a simiar issue, but it was a case of 'the dealer fixed it'. I'm very handy with a set of spanners, so I prefer to fix myself.
Propshaft bearing would be relatively easy, but my fear is the rear diff is failing. I did change the haldex oil in the hope it would help. I realised during that job that the diff oil is actually separate to the haldex unit. I haven't tried that, but my bet is that it's too late for an oil change. 😥
I had a poke around on ebay for rear diffs, and they're few and far between. It would be great of any of you know how similar the diffs are across the range (ratios and component revisions) so I can widen my options. Has anyone stripped a diff to change the bearings? They seem pretty conventional from youtube videos.
Cheers!
