Glenn Davey Posted October 30, 2015 Share Posted October 30, 2015 Hi, I have a 1972 opel manta and have had a whining noise when de-excelerating for some time which is quite noisy when driving. I took the rear axle apart and found that the pinion bearings looked worn, the cog looks part of the bearing, does anyone know whether this is right and has anyone else had this problem? I have been trying on the internet to source a rubber damper intermediate but have been unsuccessful, does anyone know where I can get hold of one? Many thanks Glenn Davey From Grays, Essex Quote Link to comment Share on other sites More sharing options...
Brown Job Posted October 30, 2015 Share Posted October 30, 2015 Oh dear. Can't speak for the A-series, but yep, it is all too familiar for the B-series/Cav 1. I have swapped 2 axles to get rid of this wear and tear and noise on deceleration, but will eventually have to go for proper rebuild when the stock of "better" axles runs out. There is a bloke in Holland does rebuilds and parts, try M&M Dronten to see if they will source for you from him, or give you his contact details. Unless anyone knows a closer to home option? You can occasionally get the B-series rebuild kits on ebay but the whole setup is quite fiddly to do, with shims etc. BJ 1 Quote Link to comment Share on other sites More sharing options...
Glenn Davey Posted October 30, 2015 Author Share Posted October 30, 2015 Hi thanks for your reply, i do think the alxe is ok? its the pinion part there was lots of slack about 2mm, so the bearings were not sitting in the cups tight, iam thinking if i change the bearings on the pinion part this will sort it but when looking at the bearing its attached to the spline drive part! thinking of cutting this off and sourcing bearings and making the spacing up with shimming after the cutting about 1mm if this makes sence? thanks again Glenn Quote Link to comment Share on other sites More sharing options...
mantasrme Posted October 31, 2015 Share Posted October 31, 2015 Pretty sure the A design is the same as the B, the bearing by the gear does come off the pinion. The preload on the bearings is set by a crush tube that slides onto the pinion shaft in the middle of the 2 bearings. When installed in the front of the axle as you tighten the nut it forces the bearings together and crushes the tube slightly, you just have to tighten it until you have the bearings tight up to the cups with enough preload (but not too much). I take axles out to a friend's place where he builds escort rally axles and gearboxes. He's been doing it so long he can feel the right amount of preload without having to set up measuring gear 1 Quote Link to comment Share on other sites More sharing options...
