hooray! I need to look at mine so I can get the bearing part number. Then I will have an extra. I remember talking to a junk yard and they asked for the VIN. I had ordered a yard compressor on ebay and they were nice enough to email me to ask. He said the one they had would not fit my truck and refunded me the money. That is when he recommended the one for an 02 trooper. As stated before, it is different, but it will fit.
I was just gonna take my compressor to a local rebuild shop and have em rebuild it. Glad I still have it.
