Part #: MR223993
Ordered: 2012 June
Paid: $87.68/ea from Cherry Hill Triplex
Part: FRONT WHEEL HUB ASSEMBLY
Left: See above
Right: 1993 Dodge Stealth RT/TT OEM
Weight:
New = 7.8lbs
Original = 9.0lbs
Most of this weight would seem to come from the much thinner disc that mates to the lugs. New = .28inches, Original = .5 inches. There is also some considerable sculpting done to the knuckle side as as well. The newer piece is much more contoured, less blocky.
There are no studs to deal with any longer, assuming so this could be a more "universal" part. Bolts come with instead. While the original configuration nutted on at the back of the knuckle, this cofiguration now bolts on through the back of the knuckle to the hub itself, hence they provide a threaded hub and lock washers for them to attach into. No nuts.
Cons:
-New studs and bolts look of a lesser strength rating and quality. Original wheel studs and hub studs were longer and heavily zinc plated. My original studs and bolts look pretty good for being 20 years old and from Illinois. New bolts and studs are raw or nasty modern zinc plated (if plated). May rust tomorrow.
-New studs are E rated. Old studs were N (or Z?) rated.
Bearing quality:
New are marked with an additional HR lettering across from the bearing number. Not sure what that stands for. Part number DACF2044M.
Old bearings are DACF2044B. Assuming just the Mth revision that they are on and not bearing load indicator.
Spin effort: The new wheel hub assemblies are considerably harder to turn than the old. Assuming after 100,000 miles they will loosen up a bit though.
