Before I take my 2005 Tacoma 4X4 to the dealership for a rear suspension squeak, what can I do pror to scheduling my appointment? I don't want to take it in more than once. I've thought about thoroughly cleaning the suspension and then lubricating all the possible components that might be causing the squeak with some type of lubricant. (Heavy duty silicone spray?) By the way, it seems to be squeaking at the front of the leaf spring -- both sides.
Knowing my dealership, they'll not pay all that much attention to any TSB's that are out there. They will try to first fix it as simply as possible.
