I just got a free trailer from one of my parent's friends and i need help selecting seals.
The trailer is a 15-year old mejier(yes the grocery store) trailer and one of the bearings was bad, so i replaced it. However, the axle/ hub are metric and its tough to get any of the seals.

I the ID numbers are as follows on the seal ridge SDA 579 VB2 31(mm inner diameter) 52(outer) 7(ht) it is a single lip seal

I found a few seals which might work but arent exact
a double lip seal with 30 inner 52 outer 7 ht
a double lip seal with 32 inner 52 outer 7th
a single lip seal with 31.75 inner 51.9938 outer 9.35 ht

Which would you guys buy? or should i keep looking? They dont make 31mm anymore. I would love to buy a whole new axle, but $20 vs 140...

The trailer is really garage friendly

if it's indeed metric and bearings are not available local I'd replace the entire axle. Save yourself headaches in the long run.

I went ahead and bought 2 30mm ID seals. They are 1mm tighter than spec so they will wear our quickly.. I will probably end up replacing the axle considering the one on there is 1000 lbs. My local trailer guy wants 145 for a 2000 axle+ hubs. Sound like a fair price?
