I've seen several accounts of broken front diffs on the 00+ UZJ100s, including some even on snow-covered driveways. Some have theorized it may have been the ATRAC system overloading the ring and pinion, despite the ATRAC Cruisers having the beefier 4-pinion diff. However, it's hard to get a feeling for how common these failures were, especially when many report very robust performance from their front diffs even over many miles of tough off-roading.
Also, was it limited to the early ATRAC models? I haven't seen any accounts of later 5-speed trucks having this issue, so maybe Toyota fixed it at some point.. I'd appreciate any insight.
