why is my rear end howling??

The rear end in my 66 Plymouth is making noise. At about 55 mph its howling pretty good while going straight or takign a curve to the right but if I take a curve to the left the howl goes away. The howl is there regardless weather i am giving the car gas or letting off... seems to be dependant on speed. Fluid in the diff is good but changed it anyway with no change.

So I am guessing a bearing is going out. I am thinking it is an axle bearing as opposed to the carrier bearings because its not noisey when accellerating.

Anyone agree/disagree?

 

Definetley sounds like an axle bearing! Run it on a hoist and listen out near the wheels....

 

probably something you ate

 

Change them both. Learn from the experience of others.

 

It's in heat and looking for a mate !!! LOL Pull it down while there is a good chance of saving it.

 

maybe it wants to be a nascar rearend, I mean the howl goes away when you turn left right?

 

Time to redo the rear end or get a louder stereo.

 

if you keep driving it ...you'll find it!!!

 

Thats what Im worried about. Thanks for the advice.

 

Been there......start tearing it apart and replace the bearings before it strands you and really tears something up......like a axle shaft or the carrier and pinion.....

 

I'm not a mechanic or anything, but OUCH that sounds painful.

 

They used tapered roller bearings on the axles, The splined end of each axle ****ed against a 'floater' block inside the diff. One of the bearing reatainers is adjustable. When you install the new bearings, you MUST adjust the axle end play with this adjustable retainer to .013" to .023". If you're running a Sure-Grip, the 'floater' is built differently and it usually comes apart on you when you pull the axles --- the two halves are held together with a roll pin. The diff. has to be dis***embled to correct this annoyance. If you fail to notice this (on a Sure-Grip) you will be unable to set axle end play.

 

Every time I read the ***le to this thread I chuckle.

 

BTW it will be the left axle bearing making the noise. Also, 1966 Mopars originally used left handed lug nuts on the left mounted wheels. Check this before you remove the wheels.

 

it could be bone dry out of oil. thats what my did. untel i shot some goo in that hole

 

full moon or axle bearings

 

My thoughts exactly! LOL

 

if there's no noise straight on and making noise on turns especially one way, it's probably a bearing

 

Yeah- My wife finds it pretty funny too....

Yikes- sounds like I may be over my head. I blew the diff in a Chevy truck and replaced everything myself but didnt chaneg the axle bearings (Was a carrier bearing problem). I have the Mopar service manual- Time to start reading up.

BTW- How do I pull the axles? I glanced throught he manual and it looks like i need pullers and things to split bearings and all kinds of funky tools. Cash is tight so I really cant take it to someone.

 

Undo the 4 bolts holding the retainer in and tap the axle flange with a soft faced hammer, they will usually pop out. If not, you will need a slide hammer.

Changing the bearings on the axle is best done on a press and usually takes a lot of force - take them to your local machine shop to get them pressed off and new ones on.

Put new seals in and cover the splines on the axles with paper while sliding them in - it is really easy to cut your new seals if you don't.

Adjust the endplay as described earlier, add lube and do a good burnout and run it up to 120 mph just make sure it works.
