When working on the bearings this complicates things because the seal is special and can not be bought in an auto parts store or catalog.(The seal has to be taken out to replace the rear bearing and is not supposed to be reused.) Spindo Seal is Made by UFP (Unique Functional Products) They have a web site http://www.ufpnet.com The kit that is used on Macgregors is #2. The kit consists of two seals, two stainless rings for the seal to ride on and two rubber o-rings which seal the rings to the axle.
Removing Spindo Seal
If you want to remove spindo seal you can. Just remove the parts and use the standard seal. Make sure to check the axle and make sure the area where the seal will ride is smooth and not rusty. If necessary it can be polished with fine emery cloth.
The brakes on Macgregor trailers are not galvanized and after a couple of years of being periodically dipped in salt water they will be in sad shape. The brake shoes rust and break the lining off, The springs rust and will not retract the shoes and the wheel cylinders will freeze up. Fortunately there are replacement sets that are available. They are all galvanized and use stainless steel springs. It is well worth it to buy the replacement sets. There are even "free backing" brakes available. These brakes are sold in the marine catalogs. (about $125)
I would suggest also buying silicone grease and anti seize compound from an auto parts store. Apply the silicone grease to the piston in the wheel cylinder and the anti-seize to the bleeder screw, hydraulic line fitting, star wheel adjuster, where the shoes rub on the backing plates and also the mounting bolts for the backing plates. This will keep things working.
