It may not be because they are a boob or a dipsheet. Every time I would take mine to a lube shop like Jiffy lube or some other chain I would look at the reciept and under greese zerks they would put chassis sealed. I would have to have them go back under and greesed it. If a person didn't know any better they wouldn't know the differance. I'm sure my neighbors probably think I'm nuts but when I bring home a new vehicle I grab the creeper and camp out under it for a while to see how it is built.
