One problem related to driveshaft has been reported for the 1998 Mazda B4000. The most recently reported issues are listed below.
Truck shudders 4 to 5 times coming to a complete stop and taking off from a complete stop all the time and occasionally also shudders in 2nd gear[truck is an automatic]. This has occurred since the 1st day I picked up the truck. It has been back to 2 different Mazda dealers after I had the transmission checked by an independent shop which gave the truck a clean bill of health and then took to independent shop for a diagnostic check where they found the problem to be the driveshaft. With this info I went back to Mazda where they regreased and repacked the driveshaft. The problem continues. I called the repair shop after I picked up the truck and told them the truck was still doing the same only now worse. I was told that they called in the dsm for the area Mazda dealers and he stated this was a "characteristic" of all the B4000 series and nothing more would be done. I have the extended warranty of 6yr/100,000 and if I take the truck for repair by other than Mazda then I will ify this warranty. I don't know what else to do. The problem is very annoying especially in any stop and go traffic[city driving inparticular] all I want to do is have the truck fixed. Any info or help in this matter would be greatly appreciated.
