Can any tell me what the stock spec is? I want to get mine changed as its noisy; I assume its a 24 spline but what does the number of bolts refer to? Replacements seem pricey but a used one seems a bit of a punt as it could be as worn as mine is. Thanks
Bolt patterns came in two bolt and four bolt. The four bolt are a bit stronger compared with older two bolt. Yes, new replacement and four bolt upgrades are expensive. Then again if your original has lasted over 100K miles with only a bit of noise and unknown service... you are doing pretty good. Have you drained and inspected the fluid already? Burnt fluid and shaving are a pretty good sign of poor service. A replacement will most likely last longer than you own the rig. A used replacement may last longer than you own the rig as well.
