1999 Dodge Ram V8 5.9L 4X4 SPORT Tranny noise?
From : Annonymous
Q: i had a universal joint do something like that once. hello all i am by no means a mechanic however i would like some input before i go to a mechanic to get my truck checked out. i am not totally convinced that my issue is 100% a transmission issue however signs do point to the area. when accelerating starting at approximately 40 mph and 1500-3000 rpm i hear a pretty pronounced rattling kinda like a can with a couple of bolts shaken... as best i can tell it seems to be coming from the middle left area under the truck most likely close to the tranny. the noise has gotten a bit worse over the last couple of weeks. it seems i can avoide the noise completely by traveling at less than 50 mph on a slight incline and i dont seem to hear anything when accelerating on a decline. i dont hear the rattle while driving the back roads only when on the freeway. the noise seems happen mostly when more force is needed to move the truck on an incline at 40 ++ mph and higher rpm. driving in od seems to reduce the noise a bit as well. the truck shifts just fine and im not noticing any performance degradation however i am very concerned about the noise. also to note is that the rear diff seems to be leaking more than usual i am planning on topping it off to see if that helps since i cant be 100% certain that the noise is coming from the middle left might be coming from the rear diff i doubt it though. any inputs would be greatly appreciated.. thanks -tim .

no magnet mount for the roof. mine is located on the bed. i physically turned it completely off and then back on. the display looks something like you would see in alien movies. i will try and remove the connectors and reconnect them. truck has been getting shaken about alot with the road conditions being what they are. i have hit alot more bumps then usual. so i will check those tonite and see if maybe that it is it. i only say that as sometimes the display works fine and sometimes it doesnt. by turning it off and on do you mean changing the display mode from temp/compass to no display if so that wont do anything but change what the overhead console is displaying; it doesnt reset any sensor. what kind of unreadable displays did you ever see sc looks like 5c or oc on the overhead display those are codes for short circuit and open circuit - indicating either the thermistor is out of range doubtful if youre not driving in the middle east or there is a problem else where in the outside temperature sensing circuit. as roy intimated a magnetic mount on the roof of the cab can really screw things up. the manual has a specific method of degaussing the roof it thats the case. on my way back from a long trip i noticed the digital compass / temperature readout was freaking out. display was randomly making unreadable displays. i turned it off and back on and still the same. turned it off again for awhile and back on again. stayed normal for awhile but then started again. was wondering if anyone else had the same problem and what was the fix or if anyone has any ideas of why it is doing it all of a sudden. i have a 96 1500 ram 5.2l extended cab 4x4 slt sport model with 145000 miles. thanks t .

it is a much more common problem than it once was because of modern casting techniques. the new processes allow much thinner and lighter castings but this by itself wouldnt be an issue if the casting was annealed before they machine it. of course that costs money and it isnt done. the newly machined manifold is actually better than a new one because your useage has already annealed the casting and it will not move again. in point of fact a gasket will not be necessary at all. however i would replace the studs as a matter of common sense. it costs very little when they are whole but very expensive if you have to pull the head to drill out a broken one and be sure to use anti seize compound on the threads. steve that would be my thoughts exactly. since he lives he did i miss something .
