Front or rear end is squeaking...

Just got a trailmaster 3 in spacer up front with a 2 in block in the rear, new 285 75 16 tires, i took it mudding a coupla days ago then never got around to washing all the mud off it for like 3 days, now when ever i put on the breaks or after i turn (any kind of roll to it) the front or rear end will start to squeak with the body rolling, is this a wd40 fix or am i going to have to take to the shop?

 

anyone?

 

Hey I had this same problem, but what i thought was a front end squeak was actually it was in the back. I conformed this by hopping in my bed and and started to hop. Sure enough it was defiantly was coming from the back. I recently got new tires and a new spare (all tires bigger than old/stock ones, new ones 265/70). Looking underneath I saw that there was a coil/spring on the spare holding it up. So i dropped the spare and jump on the bed, squeak gone! also underneath it seemed like the new bigger tires were rubbing on some metal. I put in long Gorilla tape on where the contact points (were there was dust/dirt missing) and put the spare back up, and made sure that the spare was on tight and had no play.....NO SQUEAK!
