During the recent flood in North Georgia / Metro Atlanta, My Dad's flatbed trailer was completely submerged under deep, muddy water for an ...

i have a small boat trailer which has to do 400 miles next week and want to change the bearings just in case. I was wondering, how do I know what to get. Do I just take the old ones out, look at the numbers and go on ebay or some shop or is it harder? Its a small 2 wheel trailer with a 14ft fiberglass boat on.

Also, should the main axel part of the trailer bend. Its just a square bit of metal not rotating but the main bit that joins the hubs of both wheels together. When the boat is on it, it flexes quite a lot. Is this ok?
ok, but will itbe ok for 400 miles? Im thinking of welding another bar across for more strength but dont have the time really.
Well the wheels do go in at the top a bit but the tread looks even. The trailer is very simple t-bar with a couple of smaller supports going from near the hubs to the front of the trailer. Is this bending a problem? Should I do something about it?

Should be no need to replace the bearings. All you need to do is re-pack them with axle grease. The axle is probably a torsion bar and is supposed to flex. Don't alter it.

i have a small old john boat the trailer wheel bearings have a seal on the back side of the axle (tire) but on the front side when you take of the nut there is bearings with no seal only a washer in front of the bearings.is there suppose to be a seal there also?

no, you need a dust cap at least, or preferably, bearing buddies. either way, they're an interference fit -- you just whack 'em on with a rubber mallet. The bearing buddies have a springloaded pressure plate and a grease zert so you can make sure they stay greased. pump in just enough grease until you see the pressure plate start to move. Too much will blow out the rear seal. The grease under pressure prevents water entering the hub. Then before each outing, you push against the plate with your finger -- if it doesn't move, just pump in a little grease.

i lost the bearings on the expressway. the place i took it to said they cant find the right size seal which sounds strange to me. the bearings are packed and its ready to go except for the seals. its 140 miles away and i need to get it home so i can find the right seals. its a heritage trailer and they said they never heard of it.

You will have to measure the size of the hubs outer bore where the seal fits in, And the size of the axle shaft, where the seal lip contacts the shaft. (If you can't get the number stamped on the metal part of the old seal). If you are not in a secluded place away from civilization, you should be able to go to any industrial, automotive, agricultural supply store, and give them the measurements taken from the hub and axle, or the number from the old seal and I am sure that you would have no trouble finding what you need.

I am trying to replace the wheel bearings in my boat trailer. I can only get the front bearing out. I pulled the rear seal but can not get the second bearing out. Please help. Pictures would be a big help!

First you need to find out what bearings the wheels have in them. to do that, jack the wheel up, remove the bearing cap or pressure bearing cover to gain access to the bearing nut. Remove the bearing nut (you will have to remove whatever is securing it) slide the outer bearing off of the shaft, remove the hub/wheel assembly and set it on the ground with the inner side of the tire up. There you will find a seal that you will need to replace also. Find the numbers for the seal, write them down, use a long punch and knock the seal out, clean the outer bearing assembly and find the numbers for that assembly and write that down also, the inner bearing should have fallen out when you knocked the seal out but if not you might have to knock it out too. You will want to replace the cup also so clean it off (It lives in the hub) and copy that number down too, punch the ‘race” out using a long punch and then go the auto parts store and purchase the parts you need for the wheel(s) on your trailer. There is a possibility the inner and outer bearings on the hub are different so you need to check the inner bearing for its number too. Once you have the parts, grease the bearings and put it all back together. =)
