"Managed to use the bearings fine but some of the seals did not fit anywhere and the most important pinion seal was way off. Also the pinion nut was of questionable quality compared to the original and the thread mismatched which we only discovered when we started torquing. Result was thread on pinion damaged and new ring and pinion required.Mixed feelings!!" posted by: Nigel Carey on June 18, 2014
