iphish Posted November 9, 2008 Report Share Posted November 9, 2008 Questions- see attached 1) the rubber disk at the end (middle) of the hub, I ssume covers the bearings and race, should the "button" on this rubber disk be soft, firm or hard? 2) When would be the best time to try an loosen up the lug nuts to lube, now or when it's warm-next spring. these have been on there for a while and were not maintained prior to me getting the trailer, I would rather not start snapping off the lugs.

maineskiff Posted November 9, 2008 Report Share Posted November 9, 2008 I'd soak everything down with "PB Blaster", let it sit till spring and then do your maintenece. Install Bearing buddy's when you do. Link to comment Share on other sites More sharing options...

Attachment 179590 None of the above: It is only a cover. It pops off and under it is a grease fitting. The rubber cover is only there to keep dirt out. As to part two: Assuming there is no boat on the trailer, try loosening the lug nuts. If they turn, you can remove them one at a time a put some grease on the threads. Reetighten but not to the final torque.If they don't loosen you need to apply something like Liquid Wrench and let it soak in. The nuts should be tightened in a specific pattern and torqued to spec. Overtightening is a bad as undertightening. Link to comment Share on other sites More sharing options...
Linesidesonthefly Posted November 10, 2008 Report Share Posted November 10, 2008 There is something better thsn PB. Its called Kroil. We use it at work. Comes in mighty handy freeing nuts and bolts that have seen extended time exposed to seawater on Subs.

mikep53 Posted November 10, 2008 Report Share Posted November 10, 2008 This is all good advice. Worst case scenario is if you break a lug or ruin bearings, etc.,you can buy a complete hub set will all the above greased and ready to go for about $50 each. Good luck.

jigger Posted November 10, 2008 Report Share Posted November 10, 2008 From the looks of the rubber cover. With all the white on it. Looks like you might have water inside the hub. Pull the rubber cover off and see what the grease looks like. If it is white. If it is then your going to have to pull the hub. In which case. You might as well see if you can get the nuts off. If not you might as well snap them off any way. Seeing you have the hub off. Then you can punch out the old ones and put in new. SOL # 596 Link to comment Share on other sites More sharing options...
makorider Posted November 10, 2008 Report Share Posted November 10, 2008 Get those lugs off and put NEVER SEIZE, not grease on them. I speak from experience after cussing up a storm Saturuday while helping my bud pull his new to him boat for the first time on a used trailer he just picked up. Fighting frozen lugs in the pouring rain in the sand and mud on a 'ramp' in my cove....NOT FUN Link to comment Share on other sites More sharing options...

Actually I sprayed some white lithium grease on the lug nuts and hub, that is the white that you are seeing. Link to comment Share on other sites More sharing options...

Linesidesonthefly Posted November 10, 2008 Report Share Posted November 10, 2008 Hiney, put the Kroil to it and let it sit overnight. If they fail to come free repeat the soaking. Next round introduce some heat to them. International Association of Machinists and Aerospace Workers Link to comment Share on other sites More sharing options...
pappy Posted November 10, 2008 Report Share Posted November 10, 2008 just be careful pulling on that rubber nipple it will tear Link to comment Share on other sites More sharing options...
iphish Posted November 10, 2008 Author Report Share Posted November 10, 2008 any trick to getting the rubber cover off- with out tearing it of course. Are there tabs or is it pinched on. do you grab it from the sides? or all at once. Link to comment Share on other sites More sharing options...
Irv Mac Dowell Posted November 10, 2008 Report Share Posted November 10, 2008 You just sort of pick at the edge until it pops loose. It's usually a greasy mess, so keep some paper towels handy. The hub you have seems to be the type that forces grease from the back of the hub towards the front, a very good system by the way. These hubs are usually found on Karavan trailers. It is possible to change all of the grease in the hub without pulling it by simply pumping the gun until clean, new grease is forced out the front, though, considering the visual condition of your hubs, I'd pull it, clean all of the bearings and cups; in fact, I'd probably just change them out. The numbers are found on the bearings. Karavan has a good website, and excellent service by phone, if it turns out that is maker of your trailer. As was stated above, maintenance in your driveway is far superior to fixing problems on a lonely road somewhere. Good luck.
