02 ford explorer xls 4x4
Hi everyone,
I've changed today the two back tires with size 75 instead of 70 as the old front ones. as soon as i drove outside the shop with speed around 35 mph the car started to make strange sounds like metal crushing ones with no dash warning lights. went back to the shop, putted same size of tires as the front ones. Now the "metal crushing" sound is gone, but any speed above 40 mph the car is driving like if someone is giving it a heavy push from the back and a new noise like the jet-plane noise coming from the rear axle.
i didn't know neither the "smart" mechanic that it's absolutely a No to put different sets of tires with a 4X4 Vehicle.
my question is, did the car probably gave this strange feeling of driving because of different new/old sets of tires, or an actual damage happened to the transfer case shift module or any other part?

thanks in advance to anyone can help cuz i need to figure out this quickly.

All 4 tires must be of the same size and tread wear or the "auto 4x4 system" will kick in causing the sound you heard. What you heard was the brief kicking in and out the front wheels grabbing in 4x4 mode. The different size tires caused the auto 4x4 system to sense "wheel slippage", thus go into 4x4 high mode briefly. On the rear end noise, could be a common rear differential whine noise, so have the rear diff gear oil changed or you could have a bad rear wheel bearing, so have them checked as well.
 






thanks a lot for the info, i will try to get 4 same tires, but there's also this feeling of the car being pushed in rough way accelerating to above 40 mph and also while breaking to a stop. its not a breaking issue since complete breaks job had done couple of months ago and the rear differential fluid replaced 5k miles in the past.
thank you sir :)
also the car drives very stable now
 






Things don't sound good. A reputable shop wouldn't have allowed the different size tires. I would tell you to go back to the shop that did the tires, but....
Not to be unhelpful, you need to seek assistance from he tire installers. Work something out. The more you do on your own in the meantime, the more they can put the blame elsewhere but themselves.
 






i know i made a big mistake by going to this shop ;(, i'm probably gonna try tomorrow to get 4 same tires on my explorer, but if i can't i'm gonna go to a transmission specialist so i can make sure what's going on with the trany/transfer boxes.
 






Don't forget to report back with your findings.

...no, you have to. It's not if you can, it's more of a "you must." Even if you have to eat some money. A cheap used set (same brand, roughly same wear) will be better than any new that is different sizes.

If you CAN NOT afford it right now, no matter what, you need to pull the fuse for the 4x4 module before you drive it. You can look at your owners manual or do some research to figure out which fuse (I would tell you but I don't know which fuse it is off hand, I would have to look it up). Then save up money and get a matching set of tires. Put fuse back in.
 






Fuse box in engine compartment (Battery Junction Box).
Pull out #17 (20A) and #18 (20A)

This kind of transfer box behavior (activating 4x4) is directly linked to tire size. Briefly, the system detects that your front and rear wheels spin with different speed (data from ABS sensors) and thinks that they are slipping.
