My Back Two Bearings On My Tandem Need To Be Greased Every 40 To 50 Miles. I Have Replaced Them And They Still Do The Same Thing . The Front Two Wheels Are Normal. I Do Not Know Who The Trailer Manufacturer Is,i Had It Stamped Home Made So I Could Register It. The Boat Is A 21 Scarab 3800 Lbs. What Could Cause This? Thanks In Advance.

Why do you say they need greased so often?


"Still do the same thing" Still do what??

I HAVE TO GREASE THE BEARINGS EVERY 40 OR 50 MILES SO I DON'T BURN THEM UP. I HAVE REPLACED THEM AND STILL HAVE TO GREASE THEM EVERY 40 OR 50 MILES. IT IS ONLY HAPPENING TO THE BACK TWO WHEELS. ON ALL MY OTHER TRAILERS I HAVE BEEN ABLE TO GO HUNDREDS OF MILES WITH OUT PUMPING GREASE INTO THE BEARINGS. I HAVE CHECKED TO SEE IF THE BRAKES ARE DRAGGING AND CAUSING EXCESS HEAT. FROM WHAT I CAN SEE THIS IS NOT THE PROBLEM. WHAT ELSE DO I NEED TO LOOK FOR. THANKS

Sounds like the trailer is carrying all the weight on the rear axle. You could try lowering your hitch to get trailer frame parralel to ground, if that's not it then switch out the axle for heavyier duty one.

I HAVE ADJUSTED THE BOAT ON TRAILER TO MOVE SOME WEIGHT UP AND ALSO HAVE LOWERED MY HITCH. THIS PROBLEM STARTED AFTER ABOUT A YEAR SO I DON'T THINK ITS A WEIGHT ISSUE.

Where is the grease going that you keep putting in???????

Did you replac the bearings? Did you do the races also? Where is the grease going? On the brakes or nowhere. Are the wheels getting hot? It sounds more like a bearing issue more than anything. If you remove the bearings there will be numbers on the inner part of the race. If you can't find the numbers, most trailer repair shops or parts house can match them up.

Good luck,

It has to go somewhere. Generally into the brakes. Bad seals? Brakes getting hot enough to melt the grease and have it flow past the seals?

I DID REPLACE THE BEARINGS NOT THE RACES. DON'T KNOW WHERE THE GREASE IS GOING ITS NOT ON OR AROUND THE BRAKES.I THINK I WILL JUST LET A SHOP DEAL WITH THE PROBLEM. I HAVE THE NEXT WEEK OFF AND WOULD RATHER SPEND IT ON THE WATER THAN IN MY SHOP. THANKS FOR ALL THE HELP.
