One problem related to driveshaft has been reported for the 1999 Mazda B4000. The most recently reported issues are listed below.
This truck is manufactured by Ford, it is identical to the Ford ranger with the exception of a few exterior body panels. This truck has a mechanical flaw in the drive line that feels as if the transmission bounces or "thumps up and down" when moderately accelerating from a stand still. My service center has attempted 4 repairs as per Mazda service bulletins, all have failed. Each time I contact my service center regarding a repair solution I am told the same thing" Mazda is working on a fix". I have contacted Mazda customer service numerous times and gained no information. I have been researching the characteristics of this defect. In a very short period of time I have located other Ford ranger owners with the same problem, some models dating back to 1994. When they turned to Ford for a repair, they too were put aside. What alarms me is NHTSA has many bulletins where Ford acknowledges my same complaint, some bulletins dating back to 1997 model year. I firmly believe that Ford has sold 100's to 1000's of ranger and ranger equivalents with this design defect as first quality, while knowing they are not. Today, sept. 18,2000 a Mazda representative has contacted me for the first time since this problem began. He said they do not know how to fix it. I need help in directing Ford to aknowledge this problem and release a fix. I have tolerated this defective vehicle for 25000 miles and I am approaching the end of my warranty. Another concern of mine is what long term effect this will have on other related components. Please help in anyway possible.
