I also sent this as an e-mail, but I thought I could get a faster response here.
I purchased a master set # 4-18124 for my 2001 Ford F-250 XLT Crew Cab Long Bed 4X4 where
http://www.energysuspension.com/pages/fdt3.html references that this is the kit for my vehicle. I checked the parts list and every item was accounted. The sleeves (15.10.342.39) listed in the parts list for the rear sway bar bushing set 4.5187 is not what I received. The sleeves I had were a lot longer and the inside diameter (ID) was well under .5 (1/2 inch) and the 12mm (right under 1/2") bolts supplied would not even go through them. I bored and chamfered them out to .5, went to install and found out there were a lot longer than 1.250". I tried modifying them to work, but since I don't have access to a laithe I ended up cutting them too short. I would like to see if I can get a hold of a set of four (4) 15.10.342.39 Sleeves (0.687"X0.500"X1.250") that were listed. I would think an exchange would not be feasible since the current sleeves I have are modified. This problem is holding up the reinstall of my fuel tank of my daily driver so I would like to see about expediting this matter.
