I installed 87 springs to replace my collapsed 86's and found this. I don't think I've seen this before around the boards and would be interested to hear an opinion from others why it may have broke.
My four wheel drive has also been out of service for a month now due to a bad disconnect. I bought the AWD replacement from US Powertrain to replace my faulty one but getting the old one out didn't turn out as planned......
For the record the grease from my rebuild 50k ago was dried out pretty good and the ultimate cause of failure was a broken shift fork.
Cheers,
Wallace
