Edward has a very valid point. I have a 98 F150 4x4 Off Road, Camper Package etc with LS and 145000 miles. No problem with the diff except a one time poor preventive maintenance. The diff got to moaning and groaning and I figured it was clutch time but all it was telling me was to change the lube and put in the proper additives on a regular basis. We have a Jeep Liberty Renegade 4x4 Off road as well and it started the same thing about the same time. Same cure. I learned something. You have to regularly service LS or they will give you trouble.

BTW, I have had absolutely no problems with getting stuck on the beach since day one in the Ford (I was at Mansfield Cut the second weekend I owned this truck). I very seldom put it in 4x4 on a normal beach trip. I don’t air down and I have the factory Goodyear All Terrain 17” tires. We’ve been through some very deep stuff, too. I believe the Posi rear end makes all the difference. I got over 90,000 miles out of the first set of tires and will get at least that out of the second. Yeh, I know, now that I posted this I’ll be up to the hubs the next trip!

The Jeep has Posi both ends and runs through anything except it’s a little short on ground clearance. You can road grade the ruts if you have to. Pretty scary though.

Bottom line is service LS regular i.e. like it says in the manual and use the factory recommended lubes.

esanborn- the fact you have X amount of miles on a limited slip/posi and it still works fine is good. I will tell you it does not work as good as it did within the mileage range stated earlier. A limited slip/posi is made up of a series of clutches and they DO wear out,normal street driving is wear and tear on them. Everytime you turn a corner the inside vs. outside tire movement slips the clutches.You can shim them, etc. but a locker does not wear out. It will break, but ya gotta be hammerin on it in most cases.Bottom line lockers out perform posi's hands down. Posi's have better road manners- depends on what you want.
Range rover,Land rovers are awsome anyway you lookat it IMO. under the body they are built like tanks. If i am not mistaken they came up the cable locker- pull the Handle and its locked

Good luck on whatever you guys decide, me I am a locker guy. When put it 4 low I want all 4 wheels pulling, especially down at PINS, alot cheaper than a wrecker IMO

Lower the air was adopted when bias belt tires were the norm, would not recommend it on radials, you could tear up the sidewalls real easy, they are a lot thinner and more flexible than the old bias belt tires. Best thing to do is ask your tire man ,if he would recomment dropping the pressure in your tires, tires ain't cheap, no sense ruining them. Allen

Weigh the cost of a new pair of tires against a tow truck fee. These days, the odds are in favor of the tires being less expensive.
