What you have a is a 4-way Wishbone trailer connector like part # A35W42B. The two brown wires are both the running light circuits. One needs to ran to each side of the trailer. This makes the wiring a little easier instead of having to run the brown wire to one side and then have a jumper wire to the other side.

Answer 1

The brown/green and brown/yellow wires on your trailer are for the same running light circuit. You would need to run them both to the brown wire of the 4-way.

Answer 2

Your 4-pin/5-wire wiring harness is what is called a "wishbone" type which simply means that there are two separate running light wires, one brown and one pink. This allows a separate running light wire for each side of the trailer which…

Answer 3

Did you have a 4-pin connector that had 5 wires or was it a 5-pin connector? There is a big difference since you normally see a 5-pin connector on a boat trailer with the 5th pin used for an electric reverse lockout solenoid on a brake actuating…

Your Karavan Trailer most likely uses the Grease Caps #RG04-040 which have a removable Plug #DC-RP to access the grease zerk for adding grease. If you have something different please send me pictures so I can verify what is being used. A trailer hub…

Answer 5

We recommend using digital calipers to measure the spindle. If you did not do so, you might try that. The part number 171255 that you referenced actually gives the measurements of the seal that you need. 171 means 1.71 inches inner diameter and 255…

Answer 6

There are grease seals with inner diameters of 1.687 inches, #168255TB, or 1.688 inches, #168233, that would be a better fit. If the outer diameters match the inner hub bore diameter then you can use one of them instead. Seal #168255TB has an inner…

Answer 7

If it was a 4-pin connector with 5 wires then it is called a wishbone harness and would have 2 wires attached to the running light pin so you have one wire for each side of the trailer. Typically, on a 4-Way, the white wire is ground, brown is…

Answer 8

My suspicion is that you have a poor ground connection somewhere on your trailer. The fact that everything works fine until the running lights are turned on is the dead giveaway. When the tail lights are turned on, the trailer lighting is drawing…

Answer 9

You just need to pack the bearings on hub and drum assembly #8-276-5. There's no such thing as too much grease for bearings! If it is an EZ lube hub with a grease zerk fitting at the end of the spindle you will know there is enough grease once it…

Answer 10

When the hubs get hot, and then backed into water for unloading, they have a tendency to suck water into the hub. Normal dust caps will not offer much protection. If you are looking for a bearing cap replacement that keeps out water and dirt, then…

Answer 11

You are exactly correct, it is very easy to overfill trailer hubs with grease using EZ lube spindles but they still can be helpful if used carefully. The issue though is that not all spindles have the zerk fitting to allow you to pump grease in them…

Answer 12

EZ lube spindles are more than just a zerk fitting attached to the end of the spindle. There would need to be a hole in the spindle between where the bearings ride for the grease would then fill the hub by. To be perfectly honest using EZ lube…
