NO, you said that.

I never even implied that. I haven't replaced my bearings and don't expect to for the life of the axle,and I certainly have never installed a dry bearing and it would be foolish to do so. I also doubt that Dexter ever has either.

Please read my last post, I haven't added grease through the EZ Lube except into bearings which were properly checked, hand packed, and properly installed before the application.

Wheel bearing replacement

The first thing you responded to was my reply to somebody that suggested the bearings could be installed dry at the factory and packed with the ez lube feature.

Hence, my response that the ez lube isn't designed to pack bearings, which you laughed at.

Actually I agree with your point and it shows in my every post on this thread...

Bearings should be packed prior to initial installation. EZ-lube is not (as you say) designed to pack bearings.

Here is the comment to which you have here objected....

"Explain why repacking doesn't just move fresh grease through the bearing?!"

That comment is in reference to the utility and purpose of EZ-LUBE!

Can't we just agree that EZ lube does not replace checking and repacking the bearings, and that regular maintenance brings peace of mind that pumping grease into a hole can never do?

I like the utility of the EZ-Lube system and see it as effective when used as part of a comprehensive maintenance regimen.

However, for those who don't...
I have found an excellent solution which will help prevent its accidental use and serve as a reminder of the foolish nature of EZ-Lube....

Update on my too hot to handle spindle. I brought the Scamp to our local trailer shop for an inspection and repair per Dexters recommendation. The trip was about 10 miles on side streets below 40 mph. When I got there the street side was fine, but the curbside spindle was noticeably hotter. The owner just called me back and told me the castle nut was adjusted perfectly. The bearings were fine and now re-packed. He said the curbside brake was adjusted tighter than the other side and backed it off a little. No heat damage evident. No parts were needed, I can pick our baby up in the morning. Cost: One hour labor = $82. Peace of mind = Priceless. The owner requested we show his shop the inside of the Scamp tomorrow when we pick her up. Evidently all the employees are dying to see the inside. I left it locked up with the curtains drawn.

This is the third time I have tried to respond to this due to poor internet service.
The short answer is "excellent" and certainly "reusable"
In fact on my last service I did just that since the new seals were of unacceptable quality.
I am presently searching for an old school type double lipped seal, flanged with metal to hub contact. when I find it I will change them and let everyone know the part #
If a hub seal were to be worn in a year, imagine having to service the seals on the front hubs of a rear drive vehicle, or the driveshaft yolk seal or the timing cover seal.
Fact is, I have often seen a leak on a shaft where the shaft was worn by the seal.

Case Closed

Final outcome of the hot axle. I got the trailer back from the trailer shop and after they tore the brakes apart, found no heat damage. I was told one brake was adjusted too tight and failed to fully release. They adjusted the brakes, lubed the hubs and I picked it up. I drove the same route back and the hubs stayed cool! I talked to Dexter Axle in IN. and they will reimburse the cost ($82) by mail. Since I never got the Dexter manuals from Scamp, they are sending me those as well. I feel better now! Algonac here we come!

BTW, the trailer shop owner is a big fan of the EZ lube system. He told me that you have to rotate the wheel, and SLOWLY add the grease. Done properly, it will greatly extend the life of the bearings. It sounded like an echo of Floyd's comments. He builds trailers from scratch and when we were on the ground looking at the jack point, he commented that the Scamp trailer frame was very well built. He commented that if he built one for himself, it would look just like Scamps.

Tom,
You left us hanging. You never commented on what the shop's employees thought of your trailer when they got a chance to see the inside!

Sorry about that Carl. There were 4 employees available when I came to pick it up. They had it parked in a large car port type structure and blocked by trucks and cars. The boss told me that they wanted to make sure nothing happened to it, but I think they didn't want me to come in, pay and pull it out without a look-see.

Before I opened it I explained it was bigger on the inside, and in fact had 6 rooms. They got a kick out of the:

1. dining room
2. master bedroom
3. kitchen
4. living room (couch)
5. spare bedroom (bunk beds)
6. ball room (dance floor between the living room and the master bedroom)

The employee who really wanted to see, owns a pop-up trailer but was on a parts run, so his buddy took pics. Lots of fun and they all have more appreciation for our little FG RVs.

Tom,
You are probably correct in your assessment as to why it was parked in a "safe" location!

I have lost a couple of bearings at 6000-8000 miles (in roughly 1 year of driving). A couple of people at parts stores said anything over 5000 miles is just good luck. The dexter website said grease every 12,000 miles or 12 months. What is your experience?

I think the grease zerk or something is plugged up (RV technician agrees). Any thoughts on how to unplug it?

Thanks for the advice.

I don't personally know Larry Gamble of Little House Customs, but I have read his posts for years over on the Casita Travel Trailer forum. I would venture a guess that he knows more about the mechanics of FGRV's than most of us and, for what it's worth, I respect his opinions.

"I believe in another thread you questioned Chinese bearings? For what it's worth, current production Dexter axles use Chinese bearings. Probably no way around it unless you can justify 3 times the money for Timkens. I just do my part by making sure every bit of scrap metal out of the LHC shop (axles, bearings, drums and acorn nuts included) finds its way to the recyclers and is probably shipped straight to China. At least that way our Chinese bearings stand a chance of being made from old Studebakers or Maytags."

Three times as much sounds ok to me for quality instead of scrap.
When we can no longer manufacture bearings, we will have already lost our next war.
