During routine visits to my neighborhood supermarket, I've noticed while driving the rpm meter was going up and down at a stand-still. Now the vehicle was maintenance regularly and I have had issues before I've replaced the egr valve, throttle position sensor, spark plugs, pcv valve, automatic transmission oil cooler, a/c compressor even replaced the crankshaft position sensor. The truck also seems to lack power either that being an old software that it is using or the overall drivetrain is just abysmal. There also seems to be a loud thud that comes from directly under the vehicle when engaging p r n & d. Either the bushings are worn or the driveshaft is worn. The truck has been multi point checked at a local cdj dealership and it passed. Also the ignition switch was replaced on a recall. Going at low rpms, I also noticed that when going from 15-30 mph there seems to be a delay in travel as the truck will seem to be lagging or wants to slow down when my foot isn't on the accelerator. When in motion, going around 60-80 mph, the vehicle seems to have a moderate shake as in it vibrates from the undercarriage into the cabin area. It will feel like you're on a rollercoaster and the vehicle is just rumbling down the road. It feels safe at times, but when the �service 4wd� light appears it becomes almost frightening to drive the truck as it requires more attention then any other vehicle I've encountered. Also going back to the lag, you'll hear a chain-like sound as if the differential has an issue. I've gotten most of the front-end replaced: tire-rods, ball-joints, cv-shafts/axles, struts, stabilizer links and more. Now when turning the truck, there seems to be a lack of power as well. I had the battery and alternator tested and they both came back good. I find it hard to believe that internally the truck just wasn't meant to hold up.
