06 mercury mountaineer awd question
- Thread starter Dubshot
- Start date
if its awd, no. theres a viscus coupling in the tcase (like a torque converter)
when the front ring and pinion burns up its because the viscus coupling is locked up and putting all the power to the front axle.
90% of the time the cause of it burning up is lack of maintanace/not rotating tires. if there even slightly diferent f/r it fools the tcase into thinking that 1 set is slipping and diverts power.
suddenly the maintance is cheep when you figure 4 tires, tcase and front diff overhaul.

It's got a viscous coupler, but I'm not familiar enough with that transfer case to know if it can be locked easily to make it 2wd.

I've never understood this. As a vehicle goes around corners, brakes, accelerates, and etc, how can tire sizes remain exactly the same? :scratchhead:
circumference only changes due to wear. inflation presures etc affect overall height but not how far it travels in 1 revolution.

So there is no such thing as tire squat?
yes there is

Cornfuzzled yet again...
Funny thing is, the same make, size, and model of tire can have different circumferences...kind of screwed up, but it is true...And yes, overall height affects distance traveled per rev (why do you think they are so critical of tire size and pressure???)...
I would think a catastrophic failure of this sort might justify getting FoMoCo to warranty this....broken carrier cap???
i agree, yes same make and model etc can and often do have diferent sizes. thats why for an awd car its best to get tires from the same lot, or atleast run a tape around them to match them as close as posable.
tire squat afects height, but it doesnt change circumferance ( unless you are running a tire that has ether no cords, or torn cords) all you are doing is creating an eliptical tire rather than a round one. so unless the tire is slipping on the rim then distance traveled per revolution is still the same.
generaly the only tires you see grow/shrink are drag tires, and they dont realy grow due to presure, but due to centrifical force. but then again, these are bias ply tires, not radials, so the space between the cords can expand and cause growth. a radial has a continious band of cords around the circumferance to stabilise tread and prevent growth
.
but whos guna run a bias ply tire now a days on any thing other than a pourpose built rig where you know the pros/cons?

While you're playing with it, go ahead and make sure the center diff functions properly. The viscous coupler is supposed to bias the torque distribution, but it shouldn't be locked up. Reading a little about these, it sounds like the VC has a reputation for locking up and destroying other parts since it's like driving around in 4wd all the time.

You should be able to feel that when driving ... the popping the driveline does when loading and unloading is hard to miss.
