ok GUYS . i'VE GOT A 1988 3/4 TON TRUCK . wHEN I got it the wipers just barley moved . I bought a new motor from O'Riley & Installed it . Put on those new plastic bushings . Goy a set of new blades. It had a lot ot trouble moving the blades back & fourth . After taking it apart One of the new bushing broke & I fixed it again . Well it now moves much faster .But those blade now maybe 2 or 3 months old . They bounce & make more noise than any set I have ever had . Their not 20$ blades but their sure not a pair of $4.00 blades.
