how much will cost me to replaced the rear differential on my explorer 2003

i bought my car used after a month i had to replace the water pump which was covered by wearrenty form dealer. after it was replaced the frist time it went out again within a week replaced it again and the next day it went out then replaced it and then the next day did the same. this time it worked good for about a month and a half and now it went out again so just had it replaced did"t even make it out the shop passed 3 miles and it went out. what could it be i keep being told that its a defected part but all those times in a row?.....

Ok the defrost switch is on but wnt turn off when I push the button. What's wrong? How do I fix it?

The service engine light came on this morning, i have around 130,000 miles on my explorer. I do not know what this means?

Battery dead. Battery charger starts it right away. Battery has been checked and is good. Alternator checked and is good. Once started will run beautifully. After engine off for about 3 ours or so, car won't start. When battery is dead and you open the door, the security alarm sounds.

i have heard noise coming from the front axles(i think)that sounds like a rotation noise, especially when i am decelerating. Is this a bearings or bushing problem.

My heat isn't working. When I cut it on, I hear a click, click, click noise. The air is blowing but no heat seems to be coming out of the vents.

whenever i turn on the heat the heater only blows out cold air

every time I turn on my heat, it is making a clicking sound and only blowing out cold air.

roar noise in my front right tire

Front bumper is dented, front headlights is damaged on the inside and outside. Also the front driver side door makes noise when opening and closing.

when we turn rhe tempure from cold to hot we gt just cold air and a clicking sound

everytime i turn on my heater it wont blow heat but cold air, also it makes a clicking noise,but makes no noise when i put on the air.

every time i turn it on there is this clicking

What is the normal cost for the repairs these wheeling bearings
