Campfire said:Has anyone directly swapped the 2000 & up four pinion front diff into a 98 or 99?
I was in the Sierra's yesterday skiing, and decided to give the LC a shake down on a snow covered road. Four to six inches of snow, flat, three people in the truck, rear locker engaged, center locker engaged, and it sunk. This is a stock rig as of the moment, and I had the kids get out and start rocking it back and forth. Just started to get it moving, and tick,tick, tick, clunk clunk, BAM! I had my son drive so I could push, and then I noticed the oil puddle in the snow. After digging out some ruts, we got it back about 5 feet and there was gear oil and aluminum shavings in the snow. I'm on my way back today with a car trailer to get it.
I need to know if it's a straight swap, or do I need to change the axles also.
I'll post pictures later after I get it home and drop the skid plate. After a six hour ordeal getting home, the LC is beefed up.
Thanks in advance of any help or info.
This happened to my 99lx TWICE. All under warranty. The new front diff bolts right in. I'm hoping this is the last one. Similar circumstances, but in mud.
