Here it goes...had the front differential replaced with a used one due to the grinding up front. After replacement - when turning left, right and even straight (taking off quickly) the traction control kicks (Dynamic Stability Control (DSC) / Electronic Traction Control lights illuminates) in and stays activated until I slow down or take my foot off the accelerator. Local shop (very knowledgeable by the way) replaced that differential with another used one and it still does it, but not as bad. Do you think I have another bad differential or what could cause this? It is a safety issue as it occurred getting on the expressway - had to pull over until I got control. Question: Is the LR3 front wheel drive or all wheel as needed? Gotta get this fixed!

 

It is permanent four wheel drive, so not like most AWD systems. Each wheel gets the same torque from the engine. If one slips, the traction control applies the brake to that wheel.

Does disabling DSC on the dash fix the issue? In order for DSC to trigger, it needs to pick up a difference across wheel speeds.

Are you sure the diff is the correct one for the LR3? I've heard of similar issues replacing with a diff from other LR models that might not have the same ratios.

 

Great point dj... wheel wear can also upset a sensitive system. Are all the tires the same wear level?
