Pete Lewis Posted September 23, 2022 Report Share Posted September 23, 2022 0.005" is fine 0.015" is higher than an open limit tolerance of generally 0.010" as a manufacturing standard so the hub had some runout above normal but nothing too alarming and at the drum diameter is probably fine 0.015" on the hub mounting face is excessive do make sure the drum retaing screws are underflush as if these make contact with the wheel it will distort on tightening the wheel nuts Pete Link to comment Share on other sites More sharing options...

Pete Lewis Posted September 25, 2022 Report Share Posted September 25, 2022 somewhere there would be a specification for the assembly i just use the sort of tolerances im used in truck manuafacturing of the 1962 - 2003 vintage things like couplings had a runout tol of 0.003" to 0.005" any undefined had a open tol of 0.010" unless the drawiings stated otherwise with more modern machining tolerances may well be tighter on modern cars we had some CNC stuff but the old mulit chuck lathes for facing 20" hubs and brake drums managed the 0.005 easily Link to comment Share on other sites More sharing options...
peterthegreat Posted October 30, 2022 Report Share Posted October 30, 2022 hello everyone Thought I would give you a status update. As proposed one of the rear wheel hubs was bent quite a lot, managed to get a NOS one from Mick Dolphin (very helpful guy). It seems to have fixed the issue. I used the proper hub puller from Canley classics and an air rachet to remove the hubs, worked like a dream and no need for a press or to take everything apart After putting it all back together I measure the wobble using a dial meter on the inside edge of the wheel (just in from the lip) as Front near side = 045", front off side = 020", rear near side = 030" rear off side =045" once again thanks for all your help Peter Link to comment Share on other sites More sharing options...
