I don't need to hear about how terrible these trailers are... it serves my needs and fits my budget.
What I do need to hear is where are the people that own them getting replacement bearings/seals the whole deal. The local auto shops around where I live suck and are not much help.
You can buy complete hubs with bearings & seals for about 2 extra dollars over the cost of the bearings & seals from most trailor shops,plus they come greased. Shure makes the job fast & easy! Also I would by some bearing buddies.
When the wheel bearings on my utility trailer failed I was able to find a replacement hub through Northern Tool.....
It was a simple bolt on replacement so I was able to do it myself. I also added the Bearing Buddy as others suggested, this is special cap with a grease fitting so you no longer have to disassemble the bearing to hand pack with grease.
Your local part store should have them--Timken 30205, as I recall, is the part # for the bearings...about $25 each for bearing and race. The seals, I don't remember.
If you have a Whisler near (Springs and Denver), even easier.
Iraft...I agree...for $350 I got a 2000lb Capacity trailer that works great. I purchased new bearing seals from Harbor Freight. I couldn't find them on their website so I called customer service and they helped me find the right ones and place the order. I needed them before even using my trailer the first time because the hubs and bearings came pre-packed from China....including chinese grease and dirt. I destroyed the seals taking them out to clean and regrease the hubs so needed replacements. Actually ordered a couple sets so I had them...were only 5-6$ a set.
