Great service. The parts were here in two days. Best part they were less than half the price even with shipping than the local auto stores and big box retailers were asking for.

It all started about 10 years ago when I purchased a custom built trailer. The trailer is great, but one of the stub axle/wheel kits they put on was missing a race. By the time I got the trailer home -- about 7 miles -- the dust cap was missing. Later I pulled off the wheel and noticed the race was gone and I replaced it and the bearing. I purchased several dust caps locally, all of which were supposed to fit. None of the ones off my old vehicles would work. After losing several more caps, I ordered these. Thinking I would lose them fairly quick, I ordered extras. When the box arrived, I examined the caps and was pleased with the quality. I took the beer can off the wheel and carefully hammered a new cap on. Well, now after pulling the trailer a lot, on many bumpy and bad roads, this cap has not loosened a bit. I highly recommend these caps.


Comments
These caps are still on my trailer after many more miles of bumpy roads and pulling through pastures with high weeds and brush. Still very pleased.

I ordered 3 Taskmaster 4.80-12 Bias Trailer Tire with 12" White Mod Wheel - 4 on 4 - Load Range C (Item # TTWAS12B4WMHP) on a Saturday. To my surprise they shipped them right away. The packaging was perfect and the wheels look strong and well made. This little kit trailer (cargo box is 60"x40"x24") has once been in a 3000 mile trip around the West, and the 8" wheels where almost 20 years old so I decided to get fresh tires and ordered the 12" wheels. I'll probably have to give the fenders a little more clearance but that's OK. I'm very happy with the product and service. Thank you guys!

Had to dimple the dust caps as they were to small to fit tight. Other wise they should do the job. Other than for ever getting delivered long time.

These came with a bearing kit I ordered for my trailer and they don't fit. My trailer dates back to the 60;s and the hubs are cast aluminum and, apparently almost impossible to find parts for.

Good value. A little tighter fitting than original ones on Dexter 2,200lb axle, so a bit tough to install. Plain silver steel, no etrailer.com markings on them, fine by me. I wish they were a bit beefier, but that's how it goes these days.

Thanks for the phone support. Product delivered as promised, looks great, unfortunately it is not the correct size for an old vehicle I have. I was given the wrong size, should have measured myself. I am keeping the parts to use on older trailer. Will call to see if you have correct size soon, thanks again.

perfect match for what's on the trailer now. Customer service is excellent- Adam E. is the best. etrailer also has the best information about products, and instructional videos - very good website - Excellent customer service.

The cap fits my trailer. Keeps the grease in and dirt out. It's a cap, what more can I say.



- F001518
by:

On the positive side the caps look good and feel strong. On the negative side they were difficult to install. I ended up using my bench grinder to reduce the blunt edge of the part of the cap that goes inside the hub. Additionally I cut a two inch diameter hole in a block of wood about an inch deep and placed that over the outside of the cap before tapping it in and that made it very easy to install.



- F001518
by:

I measured the hub and order the grease cap. It was installed using a piece of PVC pipe and a dead blow hammer and it sealed tight and looks great.

Thank you so much for replacing the damaged components in such a timely manner! The grease caps have been installed and the boat is in the water. I have been using etrailer for quite a while and have never been disappointed. This is my "go to" vendor for all of my trailer/towing issues.

Grease cup as advertised. All parts arrived in good condition except one. One break plate was missing the strain relief on the back. All break plates had nicks on the two green wires where they exit out the back as if the wires were nicked during installation and bent 90*. Thank you for the links to installation of the items for they have been helpful.

The bearings and race i have ordered are the perfect fir for our trailer. They are the identical match for the 1969 dilly, verry pleased with the price overall great kit. I would defiantly recommend to anyone replacing bearings and races for the 1969 dilly.



- F001518

They fit my hubs and keep the grease in for a good price. Not much else to say. I did go to the hardware store and get a pipe fitting to drive them in so I didn't dent them during installation.

Good product, excellent fit. Looks good on the trailer and snug enough to seal out dirt/trash. Should get one for the other side (for the looks but no big deal - it's a work trailer).

I ordered a hub cover for my trailer. Product was what I ordered and was delivered in an appropriate amount of time. When ordering I was concerned shipping costs were going to be high for a very inexpensive part, which occurs through other sites. However, shipping was relatively inexpensive. Good value and experience.



- F001518

Would highly recommend buying or using a cap driver. I did not and will probably re purchase this item as it fits very tight and i messed up the looks of it. The caps look great when installed correctly. Shipping was on time.

Every item I ordered worked and fit exactly as I had hoped it would. Prices and shipping was top notch and will definitely buy from e-trailer again.

    If you can provide the reference number for the OUTER wheel bearing, I can determine which replacement grease cap you actually need. You can also use a digital caliper to find the exact inside diameter of the hub bore. With a standard grease cap, the next larger size from the 1.98 inch is a 2.25 inch, which is quite a bit larger. If you're speaking of a bearing protector like the Bearing Buddy, the next largest size from the 1.98 is the 2.047 inch. If you click the provided link,...

  • Purpose of Grease Caps and How to Measure to Get Correct Size
    The purpose of the grease cap is to protect the bearing and the axle from any dirt getting into the bearing, which would then damage the bearing, hub and axle. So it is a good idea to have caps on your axle. To get the correct size cap you would need to measure the inside diameter of the cap mounting surface on your hub. Then that measurement would match up to the cap size outside diameter. The sizes of caps only vary by a small amount so the measurement has to very accurate. Some of...

    I'm assuming you're speaking of a grease cap that's driven into the hub bore. Grease caps are available in different sizes. There are two good ways to determine which size you need. One is to locate the reference number off of the outer wheel bearing. Finding the outer wheel bearing would lead me to the reference number of the race, which would lead me to the grease cover diameter. Or, you could use a digital caliper like # PTW80157 and measure the inside diameter of the hub bore, as...

Keep in mind that you will want your grease cap diameter just slightly larger than the inner diameter of the ring of your hub, but no more than about the 2 one hundredths of an inch, to ensure a secure fit.

  • Removing Rusted Grease Caps from a Trailer Hub
    Often times, especially if they are rusted, grease caps will take quite a bit of convincing to remove. When they are this stubborn, often times the caps will be destroyed in the process of removing them. Sometimes we beat them pretty hard in our shop or use a screwdriver to wedge them out. The only way to know if the Fulton Grease Cap, part # F001518, will fit is if you measure the inside diameter of the trailer hub. It should be 1.988 inches. It may be a little smaller due to rust,...
