Tanis8472 Posted June 4, 2017 Share Posted June 4, 2017 Hi guys, Having replaced the UJ's twice on my front prop shaft and then refitted it, I noticed that the front pinion area is getting very hot. Almost too hot to touch. Is this normal? It drives fine and there are no noises or clunks. TIA tanis P.S. I have changed the diff oil too. No metallic particles i could see just a little dark in colour. Quote Link to comment Share on other sites More sharing options...

Snagger Posted June 10, 2017 Share Posted June 10, 2017 I doubt that's normal. I'd guess at a bearing fault or excessive preload. Quote Link to comment Share on other sites More sharing options...
Tanis8472 Posted July 9, 2017 Author Share Posted July 9, 2017 I've got a local lr bloke saying everything but that. I don't think I can rely on him tbh. I've described the symptoms and problems but says likely gearbox windup. That would not cause a untouchable pinion and flange due to heat. I get a vibration and humming with front shaft attached but none with it off. It seems to get hotter too with Prop attached. Extra pressure on the bearings? I still think it's probably the pinion bearing. Any thoughts? Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted July 9, 2017 Share Posted July 9, 2017 A seized slip joint in the prop can damage the pinion bearings, does yours move freely? 1 Quote Link to comment Share on other sites More sharing options...
Tanis8472 Posted July 26, 2017 Author Share Posted July 26, 2017 Yes both props smooth and have new gkn uj's Got her booked in at a local place to change whole diff for good one now. That's on top of getting two bolts that hd bumper on out, they have both corroded and sheared off Quote Link to comment Share on other sites More sharing options...
Tanis8472 Posted July 26, 2017 Author Share Posted July 26, 2017 I have a feeling that the previous owners ignored the signs of a damaged Uj and that's screwed it up. The uj's were totally destroyed when I got it. Probably heat from bearing melted the grease resulting in Uj blowing. Quote Link to comment Share on other sites More sharing options...
Tanis8472 Posted October 26, 2017 Author Share Posted October 26, 2017 Well the new diff is fitted. All those problems are now gone. Drives nice and smooth and no longer getting a hot diff. Quote Link to comment Share on other sites More sharing options...
Tanis8472 Posted October 26, 2017 Author Share Posted October 26, 2017 (edited) ..and some info that might be of use to Diesel P38 Auto owners. Dont rely 100% on this info, but the D P38 Auto uses a different propshaft to all the other models in the P38 range. For the D Auto TVB000130 Dimensions:9cm x 9cm x 82cm FTC4140 for the rest Dimensions:10cm x 11cm x 79cm Seems the Auto is 3cm longer than the rest. Edited October 26, 2017 by Tanis8472 correct length statement 1 Quote Link to comment Share on other sites More sharing options...
