He has trouble with the rear wheel bearings colapsing every few years and also oil leaks on the tube at the wheel end. The bearing and seals have been changed a few time before with different brand parts. One thing believed to be causing the problem is rear end shake when cross railroad lines or hitting bumps.
Not sure where I heard this, but someone mentioned using double seals on bearing housings with this issue. Also, check the axle shafts. If they are too worn that will make leaks worse between the bearings and the axle shafts.
As for the bearings, the olderstyle ones on swing axle cars are BALL bearings. Roller bearings are stronger as I understand it. Get him to go and talk to his local bearing specialist about the problem. They may be able to put him onto a tapered roller bearing that will be stronger.
Are there any ideas out there for stiffening up the rear end on trikes? I though maybe fillet plates on the frame horns? Has anyone done this?
The easiest thing is the kafer cup style braces.
a few people have made these out of old tie rods so they are adjustable. As far as suspension goes, thicker torsion bars are also available, but I can't see you needing them on such a light vehicle.
Hope this helps.
