Well, at 184,000 miles I noticed a puddle behind my driver side rear wheel. My first thought is the rear axle seals. Used to have them replaced constantly on my 88 Crown Vic. Am I only the right track?

Yes. Replace bearings and seals, inspect axle it could be worn out. Have fun!

IIRC, there's a kit with both axles, seals and bearings. I believe it was cheaper than the parts individually. I do not have the part # saved.
It even came with friction modifier and gear lube IIRC. Search comes up with this and DANG the price has skyrocketed!!! I paid $295 locally back in like ‘11 if memory serves. Looks like I either have the wrong part number or Ford is REALLY trying to recoup their losses...

Every year they sit they have to tack on $50.00 inventory cost.........about $500.00 so far maybe??
I bought mine from a Ford dealer in Charleston that stocked about 50 kits for Cop cars......it was like $229.00 or so......back in the day!!

I believe it’s a good idea to swap to 31 spline axles when replacing the axles for bearing/axle wear because the 28 spline axles were known to be not hardened incorrectly. With the 31 spline upgrade you’ll most likely not have issues for a long long time if ever again. It is usually warn bearing surfaces on the axle that take out the seals.
Sorry for the derailment but are there any known reports of failed 31 spline axles?

I’m sure some can be found but it is well documented the issues with the improper hardening of the 28 spline that lead to their failures, of which proof is highlighted over and over on this website alone.
As far as I know first hand Moser had a bad run over a decade ago. The heating process near the ABS ring caused brittleness and flanges literally snapped clean off the shaft on high HP cars. I witnessed Zack’s prozack black car self destruct at the track. It was a real joy to back it up off the track with like six of us and a floor jack.. A few other reports around the webs came in shortly after of similar situations.

My 2004 SB car built in November 2003 had bad axles that showed up at 150K miles or so.......I believe ALL of 'em were inferior by design!!

My 04 had 1 bad axle this year. Worn groove on the axle where the bearing rides and bearings looked pretty good otherwise.
You "feel" the difference because you want to "feel" the difference. Since you just spent money on the upgrade you "have" to feel the difference
I'm looking to eliminate the double pump process I have to follow right now to get the pedal hard
