Without traction control, you've got 3 open diffs, and you're going to send power only to the wheels with the least traction. That's not terribly unusual.

 

As others have written, if the transfer case center differential is not locked it is perfectly normal that one or both of the rear wheels can spin with the front wheels not moving.

If by the dash lights you mean the Three Amigos, they have nothing to do with whether or not your t-case and diffs are working as they should.

 

Thanks for the information. The 4WD, however, is acting differently that before. We've constantly used the Rover around the property to move trailers to various places and whether in good or foul weather, when I engaged 4L the Rover moved like a tank and regardless of load capacity simply dug in and moved where required. I also noticed yesterday when testing the 4L at low speed that normally when I turned around the vehicle rocked during the turn as if it were affecting the 4L drive or wheels being engaged. It did not do so yesterday. I'm going today to have the codes tested and also put it on this guy's lift to get a look at everything in motion.

I've owned this Rover for about 16 years and although I'm not an off-road junkie, I've used the 4L extensively on my property and it just has a certain feel and performance to it, so something changed. I just don't know what that would be at this point.

Thanks once again for your advice and comments

 

thanks. Well, I suppose I misspoke regarding the dash lights. My intent was to state that when the prop shaft is removed a series of lights related to other factors of the Rover become lit. When I replace the prop shaft, they disappear. I did not mean to suggest that the 3 Amigos specifically addressed the t-case and differentials. Sorry.

With respect to your first statement, I may misunderstand the function of 4L. I thought when engaged that all 4 wheels were equally in traction mode. I had never previously observed my front wheels remaining stationary while the rear wheels spun with the case in 4L. All four wheels has previously just moved the Rover regardless of how entrenched it was or the load it was towing while on my property. With increased acceleration in 4L, the Rover simply began moving regardless. It did not do that yesterday after prop exchange and acted as though it was still in 4H. In fact, it would not move backward up the hill I was on with my trailer, something it had previously done many times without a problem at all.

 

4lo is the same as 4hi in terms of how power is routed to the wheels. only the gearing ratio is changed.

 

This post is hilarious.

 

why's that?

 

@rlrigsby I think the confusion on what is going on.

Let see if I can summarize :

• You removed the front drive shaft
• The locked the Center diff with a 10 mm wrench
• Installed a new drive shaft
• Unlocked the center diff 10 mm wrench

Since then you have noticed what appears to less traction, when you put the Disco into Low range. Sounds to me like traction control may not be engaging /and or you do not have Lo range.

Start simple put you truck in low range , then 1st gear. Press the mode switch can you get a "M to light up on your dash.

If the "M" does not light up your truck thinks it is in High and you need to see if anything is binding or disconnected underneath

If the answer is yes

1. Put the truck in LOW then drive forward and get your RPM up to about 2000-2500 note the speed you are travelling
2. Now stop put the truck in HIGH, get back up to 2000-25000 RPM note your speed it should be a great deal faster

If everything seems ok at this point it could be traction control issue, if you keep a constant gentle pedal pressure when the tires are spinning the traction control light should come on if it does not you have to check further

 

thanks for such clarification. I will go and perform those tests right now.

Thanks for taking time to help get my situation resolved.
