Ok well today I pulled out the long side axle because I noticed it had a pretty good wheel seal leak to it before my trip indicating the seal had gone bad.
I had read a few threads where people had talked about an improperly hardened bearing surface on these Poly Performance axles, after a little more research it was only a few batches from a few years ago and the purchase date of mine was borderline. and it was only the long side FJ60 shaft. most of the failures showed pretty fast in other trucks usually within 2,000 miles from a major oil seal leak. Well... since my truck is not a street truck and is a trailer queen to and from the trails it takes a long time to get that kind of miles on it. I have around 500-600 miles on them and since i had one side apart i decided to pull the long side to check it.
unfortunately I found some problems....
First thing i noticed was I had hell getting the axle in far enough to get the C clip out which could only mean a couple of things...
1.) this is why I pulled it apart to start with
2.) Why I couldnt get the axle in far enough to get the C clip out of it





3.) and then I find this... A bearing surface with premature wear... This axe was doomed from the day it was shipped out but the twisted splines seal the deal.
I am not really impressed with these poly axles, I was considering buying a replacement short side and using the pair in my other truck but now seeing this Im not so sure I will. If poly replaces the damaged long side axle then I will consider purchasing a short side as well, if not they will never see another penny from my account as it is obvious these axles that are "Designed to last a lifetime" are not up to the task of only a few years. Not to mention I am pretty sure a few years ago these axles were a lifetime warranty but the paperwork says nothing about ANY warranty at all... then when I called and talked to them a month ago they told me that the warranty has changed a few times over the years and currently the warranty is only 12 months from date of purchase (something not even listed on their website for these axles)... what this tells me is that they are changing the warranty to match the product instead of creating a better product. I understand there isnt a large market for after market land cruiser axles but the one company that makes them it would be nice if they would improve their product VS changing the warranty.
It is $470 for a pair of axles plus shipping... I found a rear 14 bolt and a steer dana 44 axle with matching 4.56 gears, the front 44 is worthless to me but the pair is $400 bones and comes with leaf springs and wheels and tires to roll it all around. so for the money I dont have to buy new gears and I can sell the 44 to get a little money back the 14 bolt may take a fast track to get under the rear of the truggy...
