Of the years, 94 - 98.5 what is the best year for equiment on the 4 wheel drive and the 5-speed manuel, any problems, I know that new is usually better especially with the 215hp pump but anything else that stands out?

 

The 98 mite be best....if your lucky you'll get the new gear housing and dont have to worry about the KDP falling out

 

Is there a way to tell from the outside if you have the new and improved gear case , or if your old one has ever been replaced ?

 

98 12valve 5spd

The 98.4 12 Valvers are a rare machine. At the 98.5 mark they had the 24 valve come out. In 98 you got the first year of the quad cab also.<br><br>Rare truck, but I would like to find one.. 98.4 12 valve 2500 Quad 5 spd 4X4.... I'll just keep dreamin... [undecided]<br><br>J-eh

 

The gear case was changed in 98 with the 24 valve engine or 98 1/2 model. However, Cummins continued to use up the old style cases on hand. Having a 98 model 24 valver doesn't mean you're exempt from having a kdp problem. It has happened to members at the TDR site.<br><br>Jerry
