Video Transcript for Redline Dust Cap Driver Tool Review

Today we are going to review the Dust Cap Driver Tool. This tool comes in three different sizes. The one we are going to use today is for dust caps that are 1.986 inches and this is going to be part number 290-991. This is the one we are going to use on the demonstration today but notice the other two part numbers are pretty much identical accept for the diameters. Then we have got the dust cap and we are going to uses the 1.986 diameter and basically all it does is sit in place like that and use a mallet and drive it into the hub. 00:30

Lets use it in actual practice. There are a couple of ways you can do this. You can set it on there maybe give it a couple of taps just to help get it started or you can start the whole way and drive it in. It makes installing the dust cap that easy and you do not have any dents on the outside of the cap as well. With that, that will finish the review of the Dust Cap Driver Tool.

Definitely worth the investment. Makes removal and installation of most 2.72" dust caps a breeze


The bearing and race replacements I ordered for my trailer have held up well a year later with 7K + miles on them.

I felt fortunate however that they were not damaged despite how they were shipped from ETrailer. After all these are precision bearings and machined races.


I bought all three sizes. I service a fleet of pickup trailers in the oilfields and after so many hubcaps, you'll look for something to do the job better. Reinstalling an old cap isnt too bad most of the time, new ones are where these tools shine. The majority of new hubcaps will not install easy, without some good heavy persuasion. And its just a sad sight, a bent, bruisied and beat up brand new hubcap. But this tool will make you proud.

I've noticed hammering on hubcaps can lead to them actually falling off down the road (pun). And the other issue is with the cotter pin inside. If the cap is dented badly, it will rub on the cotter pin or grease zerk, if it didn't already break off. Its not easy to cause this but it is possible.
Breakdown of why I bought these:
50% getting so incredibly annoyed that the cap just won't go on and being tempted to use a BFH. 30% because a newly overhauled trailer looked like h-edouble hockey sticks when I got done with it. 20% noticing hammered caps seem to fall off easier, later.

These are extremely well made thus far. I was surprised how nice and heavy they were, no quality skimping here. The cup end is made of a perfect thickness, you could toss this thing around no worries. The shaft is solid or at least thickwalled judging by the weight. And the end is a separate rounded off piece just waiting for the hammer time.

Note, the length I'm not sure on yet. The end sticks out just above the hand when grasping tool. Maybe nice to be an inch longer? Not sure yet.
Other thing I noticed is how close fitting this is. Not a con, but just keep in mind its not gonna be good for installing old beat up caps.

For removing hub caps look into SnapOns GCP10 pliers. Together, these tools are the perfect pair.


Hi I’m a fleet manager for large company we use large hub cap tool on about 30 trailers the large caps are very difficult to get on with out the tool buy the tool make life easy etrailer IS THE BEST TO DEAL WITH THANKS.......

An absolute must have for saving the wheel bearing dust cover from hammer marks when installing. Sure you can use wood but this is so quick and saves smashed fingers and scratched/dented dust cap.


Indispensable tool, not only for installing but also removing dust caps. I will have one of these for as long as I own a trailer.


This product was exactly what I needed to install the bearing cap on my trailer wheel. I had to replace the damaged one with a new one and this did the trick. Nothing else i tried worked, so the purchase of this tool was well worth the price.


If you've ever banged up a dust cap trying to get it back on this is the tool you need! Easy and quick and DOES NOT dent the cover.
I bought all 3 sizes since I work on trailers. Time saving tool and time is $$$$


these grease cap tools work great! used on my old Plymouth without distorting the grease cap...put it over grease cap and give it a couple of whacks!..a nice tight fit..the bigger ones will work with most other truck, .suv, van grease caps!..a must tool!! Love um!!


I own these in all the sizes. They're excellent quality and will keep your caps looking new, as well as making them easier to install. A great tool.

I still recommend these whenever I can. I have all three sizes plus a duplicate for my boat trailer so I can keep one in the truck.

Excellent tool for cap removal and installation. I have been ruining caps for years with hammers and screwdrivers. This tool eliminates the damage and speeds hub maintenance. Worth every penny.


Excellent quality, superior customer service. ETrailer sued makes my life easy!


Never seen this type of tool before. Sure keeps the dents off the dust caps


great tool! simple idea, but very effective to avoid damage to the hub cover


Sure makes it easy to install the hub caps without distortion. Must have tool.


GOOD product very heavy duty


I think it is functional, sturdy, and a necessity! Fits perfect!


It worked just like it is supposed to. There are no moving parts except for the hammer. Just be sure and keep your fingers out of the way.


Product was received promptly and is exactly as advertised. I have used it for the designed purpose, and it worked well.


it is excellent, would like to know if there is one larger available, meaning that fits larger dust cowers.


Excellent tool and customer service!



Works great


Polite helpful, quick delivery.
service! Thank you.

  • Where to Measure a Dust Cap for a Driver Tool # 290-993
    You would need to measure the outer diameter of the end of the grease cap that fits into the hub. Driver tool # 290-993 is designed for caps with a 2.72 inch outer diameter. If there isn't one that matches the size you have a small block of wood works just as well.

  • Will Dust Cap Tool Work for Recessed Cap
    The Dust Cap Driver Tool # 290-992 could work despite the recess you have. It measures just about 5" long so just be sure you have a bit more length than that or there is enough room for you to be able to maneuver the tool. Also keep in mind that this tool works for grease caps that have a 2.44" outer diameter. There is also a Dust Cap Driver Tool for 2.72" Grease Caps # 290-993.

  • Dust Cap On Trailer Hub Keeps Falling Off
    If your hub ever made hard contact with a curb or something similar then it is possible that the center bore isn't true anymore. It is also possible that the cap was not driven in evenly. That coupled with centrifugal force will cause it to fall off. To drive in a dust cap evenly you can use a dust cap driver tool. We have a couple options: # 290-992 works with 2.440 inch grease caps # 290-993 works with 2.72 inch grease caps Using a driver tool will ensure that the cap is driven in evenly.

  • Grease Cap Fit for M1101 Trailer with Hub Bore 2.694 Bore
    The closest size we have is 2.72 inches and is the part # RG04-120. It's going to be pretty tight but since the caps are tapered as well as most hub bores it would be your best option that will fit based on a previous customer coming back and saying this fit your exact trailer. For a drive tool you would want the part # 290-993 to make driving on the cap easier.

  • How to Remove a Trailer EZ Lube Grease Cap or Dust Cap
    EZ Lube Dust Caps, like # DC200L-DCRP, have a rubber plug that can be removed to access the zerk fitting. The rubber plug can be removed by gently prying it up with a flathead screwdriver. If your dust cap is in good condition and you want to avoid getting dents in the cover, you can use the Dust Cap Driver Tool to remove the cap. Simply slide it over the dust cap and then use the leverage created by the handle to gently pry on the cap in different directions until it begins to wiggle....
