Hello
Not a good sign, probably carrier bearings in the rear differential remove your inspection plug and see if there is a bunch of metel shavings on the plug there probably be a little then remove rear cover and see if there is pieces laying in the bottem of the housing if there is you will need to replace it . Your best option would be to check at a salvage yard and look for a used one and replace the whole rear end assembly it can be pretty spending when you have someone rebuid the original one. I have beeen able to pick them up for around a couple hundred with a warranty
good luck
Chris

Engine whine, low howl from under car, rear end noise


well i dont know about the howl but i would definitely get the rotors resurfaced they are not supposed to stop at one point if the tire is in the air and spin it by hand the tire should come to a smooth slow stop and bearings are very tricky to spot i would replace them just to be on the safe side

A howling noise in the rear end.


The final drive (diff) could be low or out of oil. Have a look around inside of the rear wheels for any oil leaks. Also ckeck the pinion seal. But get oil into the filler plug before you do anyting else.

I have a loud howling noise coming from rear end.it does it when i am on and off the throttle and it is very loud.2004 dodge slt4x4 5.7 hemi


Hello! This could be from a few things - you could have a differential pinion gear that is misaligned and that will cause a howling noise - or it could also be a wheel bearing. Check your differential fluid and it might be worthwhile changing it.

Hope this helps and good luck!

I have a dodge ram 1500 4x4 quadcab the rear end is howling and making noises when i am on and off the throttle


The problem is almost always caused by the clips that hold the clutch disc in place on the po-si rear-ends.The clip will come lose and catch between the carrier clamp and cause metal parts to be deposited in the housing causing the front and rear pinion bearing to wear. Howling while accelerating is the rear pinion bearing. Howling while decelerating is the front pinion bearing. Sometimes you can get by with just replacing the clips and pinion bearings. Clips can be ordered out of California. For around $70.00 .The dealer will want to sell the entire assembly. Which does not include the pinion and bearings. The longer you go the more damage that will be done. If you can't do this yourself. No one is going to repair just part of the assembly and warranty.

the howling sound could be a window with a little opening, check if your window was totally closed. the clunkin? or clickin sound you hear could be the road salt or ice thats being thrown to your mud guard by the wheel. anyway an actual inspection is recomended, pep boys can do a courtesy check for free.
