8 3/4 rear axle advise and parts required

[toppers33]

Hi, does anyone have a pair of the later style MO400 snap ring rear wheel bearings for sale for a 1966 Dodge Coronet 440 8 3/4" sure grip rear axle?

I ask as I've just given my car a good bit of use over the last 2 weeks (in all weathers) and over the last few days the rear gave the typical noise symptoms of a wheel bearing failing. I've taken the axle shafts out expecting to see tapered bearings but was a little surprised to find no end play adjuster as the manual suggests I should have. So having done a bit of research it looks like a previous owner has converted to green bearings (1st generation without the snap ring). As I don't have the original parts the quickest fix will be to replace with the MO400 style. I've read the lengthy threads regarding the pro's and con's of this style bearing but as someone has already made the choice for me I'm kind of stuck with them unless I can source all the original parts to put it back to tapered. The button piece from the centre of the diff will be missing so going this route is a big job that I won't be tackling this summer.

The drivers axle looked like the outer seal had been leaking as the bearing grease was accompanied by a lot of water and going rusty, the passenger side inner oil seal looks to have failed as diff oil has made its way into the bearing. So both sides need doing.

My questions are:

Does anyone have a pair of snap ring style (MO400) rear wheel bearings spare that they want to sellavailable?

Does anyone know a UK supplier that may have some in stock including inner and outer seals and the 'wedding ring'? I will try Rodley Motors tomorrow as they are local to me as I'd already asked them to check stock of the tapered style last week whilst I was away. I doubt they'll have the ball bearing style though.

Any help appreciated. What I thought would be a simple tapered bearing and seal change out now has me a little concerned as I've all sorts of runs and shows coming up that I was hoping to take the car on. Not a big job but as I'm new to Mopar ownership I'm hoping to find a UK supplier who may have stock available rather than waiting for them from the US ;-)

Cheers,

Lee

If someone could please confirm these are the green style bearings I'd appreciate it.

OK, I've ordered and received the rear wheel bearings from Hauser (super fast delivery too), old ones are off and ready to press new ones on tomorrow.

I can't believe what little parts hold the rear drive shafts in! There's only the retaining plate pushing against the snap ring to stop the bearing thrusting out and then there's only the interference fit of the bearing to shaft to stop the shafts thrusting out. It obviously works but there seems not much holding it all in!

My stack up of parts is hub/drive shaft retaining plate, gasket, brake plate, bearing, wedding ring. These green MO400 snap ring style bearings don't have the stepped shoulder like the 1st generathing bearing that I removed does. Just an observation, I'mn sure I'm not the only person to be surprised by how little mechanical clamping there is to keep it all in place!

Soon be back together and ready to be enjoyed again.
