4WD on hard surface?

I've noticed is a lot of vehicles(newer mostly) dont match front and rear gear ratios. EX: rear 4:10 front 4:09 this is fine if there is some slippage of the tire but if no slipage is occuring wear faster.

This had been an enormous problem for Ford when they released a Ridgeline-like coupé-utility with 4WD in Brazil, but the difference between the axles was greater. More than 35mph with the 4WD engaged would damage its rear axle severely...

My LR is 4HI at all times/ 4speed. But if I have the diffs locked in Hi, I cannot exceed 40 MPH on a slippery surface. If I'm in 4Lo, it's really amazing if you can push it about 40. If I have the diffs locked, cannot exceed 40 MPH. This allows for each tire to adjust itself for better traction. I almost never need to lock the diffs cause of all the other electo stuff it will incorporate. Also, it it is kicking in the TC to much, lockers will automatically engage until I press the button. Don't know about other not all time 4hi trucks.

It's not supposed to have any damage to the driveline because of the central differential, just like the Hummer, current Mercedes G-Class, among others...

Hardest part of being in 4wd on any hard surface is turning.... then you have front and rear fighting each other.. and you also have the left and right fighting each other

On some dirt drags ive raced If its a long and we use 4high... halfway down the track i would kick it out of 4wd...because it would slide into 2wd..... If it was a short track we had to run 4low... You had to leave it in through the full track.. my 208 transfer didnt have 2low

If you have lock outs... and you use 4low (just for the gearing) leave your lockout on free and you can run as fast as you would like (considering the locksouts work)

Left/right won't fight each other in the front unless you added a locker or LSD... It's the front/rear that'll kill each other...
