Rear end leaking in a 2005 dodge ram 1500, what problems could that lead to.

What you need to do is check to see if your getting current coming from the key switch to the starter. it's the thinnest wire that goes on the startex, that little round thing on the starter. if no current check the fuses you will see one as ( ST ) that is staring fuse. If fuse is ok then you check the starter relay and if that is ok then you might have a broken wire. to make sure the starter is working you could put the van in park and connect a jumper lead to the startex where the small wire runs to the starter and touch the next end to the B+ or 12 volts side of the battery and if the starter works then you have a broken wire.

it mite have a axle seal leaking or a wheel cyclinder mite be leaking causing the brake shoes to grab and stick ,

if your car still in the warranty, you can take it to the car dealer, they will fix it.
or you can try this: transmission out and left your down pipe loose, you could grab it and move it up and down 2-3 inches. Tightened it up and the light didnt come on for 2 or 3 weeks. Check to see if your exhaust before the sensors are leak free, and watch out for gas.

that is not a good noise. you will need to remove the rear cover on the rear end I think you will find a lot of broken pieces, sounds like you need a ring and pinion gear set......SORRY

It sounds as though you have a bearing issue in the rear differential, but hard to say with limited info

i dont believe the ratio is supplied by the vin but the ratio is written or stamped on the tag on the rear end, or front differential

remove the driveshaft, clean the nut holding the driveshaft coupler to rear end pinion shaft, mark it,now loosen the nut counting the turns so you can put nut back to exact amount of turns, then use a chisel and hammer to remove old seal, clean area good and install new seal and check oil when done, hope this helps.heres a diagram.

The hose is only an extension to elevate the vent. Trucks have these so they can be braver about crossing axle deep water.. The plastic piece on the end is somewhat of a chk valve so the hose isn't open to dirt and road spray.It should be cliped to the frame to stay elevated.

i had the same problem with my 98 dodge durango it has the same 12 bolt rear end and what i had to do is change all my bearings
