Hawke - front stub axle, retaining circlip
My 50 year old Hawke DL11, has lost one of its circlips that prevent the front stub axle from coming out of the upright. Of course, it cant, as the brake disk is surrounded by the caliper. However, what it did, was push out the inner wheel bearing, so ultimalty the bearing could become detached, which would not improve my afternoon. It also gave me a braking issue, as the disk would just move from side to side.
I would suggest that using a circlip to hold an axle in place is a pretty poor design. Any ideas to improve?
At least in the 23 years I've been racing this car, it's the first time this has happened.
Spiral retaining rings may be an option

Also check the "eared" retaining rings themselves for best orientation when installing. Because they are typically stamped out of sheet stock, one side of the ring will have a quite sharp 90 degree edge, other side slightly rounded by distortion as the punch penetrates the stock. I think it best to put the "sharp edge" facing away from the bearing race to have maximum ring area mating with the groove shoulder where the thrust load is reacted against.
McMaster-Carr carries spiral retaining rings (thrust loads below are for fitment to 1.25 inch diameter shaft where "eared" retaining ring has 7460 lb. thrust load capability)--
