Jason came across this fantastic HDJ81. It already had a lift, factory winch, factory swingout, heated seats, fridge console, altimeter, luggage rack delete, hatch wing delete, e-lockers, the turbo diesel, and only 46k miles. |

Jason camps out with the family often. |
Jason was pulling some shrubbery out using reverse gear..... |
....when he heard a good sized BANG! noise and when he removed the front drain plug he saw this. |
He then pulled the 3rd to find missing teeth on the ring gear. |
This is where the real mystery begins....How can 6 of the 10 ring gear bolts be loose like this?.... on a 27 year old Landcruiser with only 46,000 miles miles on the clock... on a 3rd that appears to have never been tampered with? |
These lock tabs appear to have never been disturbed. How do they get this loose by themselves? |
Upon further teardown, how do ALL 8 of the case bolts loosen up like this....with one sheared off head? |
Where is Sherlock when you need him. |

The case halves are distorted....it wobbles back and forth a little. Totally unusable. |

Cracks. |
Same crack....different angle. The center case is junk. |
Jason found a deal on Ebay for the whole elocker case....loaded with the spiders and side gears for only 550. I have only heard of 2 other occurrences like this...one was with one of my customers a couple years ago.... and the other was from someone that called me up with the same loose bolts. Case sub-assy 41301-60060 |
A good 410 ring/pinion gear set was found for Jason (shown at top of pic). |
