Reverse is where most of these diffs give up. Well documented down under.

There has to be a wrecking yard with a housing.

Not to be stupid, but could you weld all the holes shut and then grind it smooth on the inside and reuse? and if that works, send me $500 for my idea!!!!

Good idea. You really could weld up some pretty good protection that way. I don't see anything that would be a drawback to that.

BTW, my aggreeing with you is worth at least $250 in endorsement money. :idea:
 
Maybe 300 bucks. I would definitley ask someone.

My brother use to work at an engine rebuild place and they would weld and grind anything back to reuseble. Never heard of them doing a diff housing.

Thanks guys for keeping me in mind with all your ideas. I'm stuck at work for 48 hours, so the LC is sitting in front of the house with a pan under it and I just sit here thinking of all kinds of repairs. The MillerMatic 175 is sitting in the garage, so the thought of "filling holes" is not out of the question. I have to get it apart first before I decide what exact path I'm taking. And yes, as much as I can remember, it was in reverse at the time of detonation.
 
If I read the parts list correctly, the differential carrier lists for $1100.

You guys are awesome! I called CruizerDan and sure enough, the assembly (#1 in the picture) lists out for $1100. I called the local dealer and got a deal for $899 and it will be here TOMORROW! Dan did beat the price, but with shipping i save about $40. I called the salvage yard that quoted me$1500 and told him I was getting a NEW unit for $899. He said "I'll Guarantee you don't get the housing". Whatever :cheers:

They have idiots like this everywhere. I'm buying a Harley and there are dealers that sell for MSRP and then there are dealers like the one in Las Vegas/ South Utah, that sell for several thousand over MSRP. I told the saleman at the Las Vegas dealer that if they wanted to sell one for MSRP I would buy it (because I told him that the dealer in Salt Lake would sell one for that price) He did the same "kind" of comment you got from the salvage yard guy. Glad you got the right information from the wonderful members of IH8MUD.
 
Nothing really to add here other than to mention that the 2 pinion 98-9 diff is superceeded to the 00-02 4 pinion diff. So, buying a new one does give you the 4 pinion job to go back in.


:cheers: D-
 
Well, I'm trying to end this. I got it out, pulled the cover (which also had a crack in it), and here's what was in the JackerJack Box. Notice the pin sheared in the first pic, and the remainder of the pin stuck in the front cover. Most of the spider gears were caught around the pinion gear which was missing about half of 4 teeth. I couldn't get the camera to focus down in there. So now it's put back together and get new tires and a winch. Have a nice day.
 
PLease put that old diff in a box and mail to Toyota with a bow on it. That would be to funny.

Glad you got it fixed.

I have had my 99 LC for 2 years now and have been very happy until I've started reading this thread! Had a Jeep Grand Wagoneer for 14 years drove it into somewhat nasty stuff with no difficulties or breakdowns.

This "exploding axle" happened in 6" of snow?? Then one comment was something about "the way these things go through diffs"???? And another comment about being careful about reverse gear??????

Did I just purchase a problem waiting to happen if I do venture off-road in my Land Cruiser? I read many stories about how bullet-proof they were and became very convinced that my purchase was wise. Now, I don't know.

Is this story in this thread a rarity or is axle/diff problems more pervasive?

Thanks for your comments on this subject

Compare your model-year Cruiser with a model-year Jeep Grand Cherokee...then let's talk about breaks and busts. I've led 2 trips where Grand's broke motor mounts and rammed their fans through the radiators. I rarely go on a run with Jeeps where some Jeep doesn't bust something.

With a Cruiser we don't need to rebuild our trucks. With a Jeep, you need to re0build about everything in order to safely wheel, though then itisn't a Jeep any longer.
 
vak01,

What year model LC do you have? The 00 and newer have a 4 pinion front diff vs a 2 pinion front diff in the 98 and 99.

Regards,

Do a search. The members of IHMUD use their LC's harder then any normal owner. This search will tell you if this is a problem or just a fluke.

It sounds like you did research before buying your 99 100 series. The 2 pinion diff (98 and 99) versus the 4 pinion diff (2000 on) has been well documented here on Mud.

It is illogical to assume you just bought a well engineered, highly capable off road vehicle that is waiting to let you down if you "venture off road". It makes sense however to understand potential weak points in ANY vehicle when using them in a harsh environment.

Simple answer: No, you did not just purchase a problem waiting to happen. Venturing off road introduces all kinds of potential situations and issues and this one, while rare, falls into that category.

OK, but THIS thread here discusses a failure from simply driving onto a snow covered road and then getting stuck and then trying to get out. Original writer comments that he rocked the car in a particular fashion, in a particular sequence which resulted in a radical problem. One follow-up writer commented that the original writer did nothing out of the ordinary during his escape.

This is what I'm concerned about ... the solution path the original writer described, and the follow-up confirmation is probably the same solution path I would have taken, too. Maybe even some other drivers would have tried that solution path, too.

Is the solution the cause of the problem or is the problem inherent in the vehicle?

Of course one should know the upside and downside of his vehicle, common sense. I knew all too well where and especially where NOT to go in my jeep. Now, through these discussions, I'm trying to gain the same skill set. No reason for me to reinvent the "LC", so to speak.

Thanks for all the help and positive input.
 
As the "Original writer" let me defend my STUPID actions.
A. I was the solo vehicle. No buddy along and in place with a tow strap or winch.
B. "New to me" vehicle, and had not purchased snow chains yet
C. Had not put the winch on yet.
D. I was still riding on those stock Michelin AT M/S (NOT!) :doh:
E. Didn't even have chains with me.

I broke the rules of offroading, did even more stupid things trying to cover my butt, and am now having to pay for them. When I did get stuck, I was on a bridge. Under the 4-6 inches of snow was 1/2 inch of ice. I am suprised that the LC didn't take to the rocking, but after replacing the front diff on Sunday, I went to reinstall the front driveline and found it out of phase. A little more inspection and started finding a few telltale signs of "somebody been here before". If you wanted to hear LC bashing, you should've been in my garage when my Jeep owning buddy showed up. Of course he forgot the three times I've towed him home. I was a mechanic for 16 years. They all break, some more than others. When I get done, I'll know what's in it, and who did the work. And before I get out again in the snow...
