Failure Mode of CV's ?, ... what actually will occur Options

[vesnyder]

I am getting a creaking noise coming from my axle CV, as best I can assess, and was curious how these will fail? I took them apart and repacked them with grease, but hod little to no affect. Will the inner CV just disintegrate and I will no longer get power to the wheels, or will something more catastrophic occur? I am debating wether I should wait until the noise gets unbearable, or fix them ASAP? It does not seem to be getting any worse? Thanks

I think Mueller had a cool way to adapt the Type 1 CV. as 914 units are hrd to find and pretty expensive.

Creaking and clicking or BANG is CV
Groaning/ howling is Wheel bearing.

Whenyou take off the VC joint from the axle pull it apart and you can see the wear marks in the form of grooves in a bad one.
as in the bang is where there ia a crack in the cage. Typicla cause is spinning tires that suddenly stick and generate high loads.
These little CV's were designed to stand up to itty bitty skinny tires and 100 HP cars.
I'm suprised mine have held up as well as they have.
