i have 99 3500 5speed, 2nd Gen
, loose steering i think this is a common problem with most of the 1st&2nd gen cummins truck, low fuel pressure supply from the lift pump will kill the injector pump also known as a VP44 pump, replaced one. the original NV4500 5speed have a problem with losing 5 gear"poor design" there is a updated shaft and nut to fix this, lost 5 gear 200miles from home pulling a trailer. "53" block casting number, has weak spots in the block wall around the water passages on the passenger side that will split. there were three castings of the blocks "53's" were bad. mine has probly close to 300,000miles and nothings gone wrong with the mighty cummins, just had problems with all the dodge part around it.hahaha. i would look for a 1st Gen "mechincal fuel pump 12valve, same 5speed problem, there is a dowel pin pressed in the block to center the timing gear cover it will work its way out and fall into the gear trail and crack the timing cover at least, there is a simple tab kit the covers the pin and holds it in place. just have to remove the fan, pullies and timing cover to install it." or a 3rd gen CR fuel system. sorry don't know much about the 3rd Gens other than the auto have a electrical problem dealing with a wire coming off the altinator that affects shifting but doesn't happen to all of them just a few.
