Just got done repairing one of my small trailers. You would never guess how 8 lugnuts would end up costing close to $500.00!!! One of my employees with the brain of a mouse decided to put the lugnuts on backwards. 3 days later he calls me up and says the trailer lost a wheel and the other side is wobbling! he is sitting on the INSIDE median of the local state hiway. Here is the break down: Times are approx., Trailer is 5x10 with 20.5x10x16 w/ 4 hole rim. 45 mins. for me to go get a trailer and drive to him. 75 mins. to get his trailer on mine including the mower. 30 mins. to drive to shop. 30 mins. to get his trailer off mine and into shop. He goes home at 2:45 pm and does not return till folowing am, (arrives late) Meanwhile, I spend 30 mins. on phone trying to find a wheel locally. end up having to order one that will take 2 days. Following day I have to rent a trailer so he can do his job. 60 mins. removing what is left of the Lug nuts with a torch, drilling holes slightly larger for new studs. Re-welding back sides Studs and nuts cost about $12.00 2 wheels cost about $65.00. had to get one new tire, the other is lost in hiway heaven. Tire cost almost $40.00 Add in lost time from him not being able to keep his jobs on schedule and my time (which is worth at least $100 per hour, I had to post-pone my work) His ignorance cost a bunch of cash. Word to the wise. DO NOT ASSUME your help knows what they are doing just because they can drive a truck and pull a trailer.
