I took my F-150 over to a buddies garage and we put it up on the hoist and then started the truck with it in gear.....I was surprised to see that the driveshaft wasn't turning true...it had a wobble in it!!
I decided to take it to a well known Drive Train shop in Ottawa....THEY REPLACED THE U-JOINT that the Ford dealership changed in November
....the mechanic told me that the new F-150's (2004 and newer) have a different style of u-joint and in almost every case, the driveshaft will need to be re-balanced and Ford does not offer that service.....he said that in most cases, Ford normally tries to convince their customers, that the driveshaft needs to be replaced!!
Kanata Ford charged me $405.67 to replace the u-joint. Malmberg Co. charged me $249.81 to replace the u-joint and balance the driveshaft!...the vibratioon is gone and the truck drives great!!
I will NEVER take my truck back to the dealership or will EVER buy another vehicle from them again!!!
