Hello George,

The Dexter bearing kit # DX66ER is for a 2,200 pound axle, straight spindle with both inner and outer bearing L44649, I attached a picture of the what comes in that kit. I am sorry but Timken does not have a bearing kit with both inner and outer bearing L44649, so you will have to piece it together.

For each hub you are working on, you will need:

(2) Timken Replacement Trailer Wheel Bearing - L44649 # TMK29FR

(2) Timken L44610 Replacement Race # TMK55FR

(1) Timken Grease Seal - Single Lip - I.D. 1.500" / O.D. 2.332" - 203013 # TMK89ZR

(1) Replacement Spindle Washer - Tang Type for E-Z Lube # 5-101 - this is the one that comes in all the Timken kits

(1) Cotter Pin - 1/8" Thick x 1-3/4" Long # 165649 - also included in Timken kits

What kind of trailer are you working on?

I purchased a complete Timken bearing and race set for my RV 2 years ago. They fit perfectly and they have exceeded my expectations.

This is my second bearing, with two different travel trailers, I replaced my Chinese made axle bearings, American made has better quality than other brands. Burn marks on Chinese made bearings, I replaced it with it Timken, little pricey but it’s worth it.

@Manny In this day and age, you definitely get what you pay for. Spending a little extra in the beginning, usually saves you some heartbreak in the long run. Thanks for the response Manny =)

Replaced my original bearings last year with Timken ones and so far, love them! I’m heading to Canada with the dogs and wife in about a week, and will not be worried about them. Jerry
