After extensive repairs including front axles, the transfer case, front brakes (rotors,calipers,pads) front left wheel bearing assembly and front end bushing my mechanic is telling me it needs a front end pinion bushing and states its an extensive job and not worth it. He removed the drive shaft for me to drive it home but states the transfer case will go again if not put back in. I left the vehicle with him for what was supposed to be the final job of "a bushing" in the front end. The car was running fine except foe an occasional clunk which he said was this bushing. I did hear what sounded like a brake pad going on the right front but thought that odd as he had just done all brakes front and back within 6 months. When I went to pick it up he told me it was 3 bushings not 1 and now a passenger side front wheel bearing. Now after picking it up the car drove horrible! He told me after taking the front end again its a pinion bearing and a really extensive job. I've put a lot of money into this car and feel i'm almost there instead of getting a new one. Do you think it's worth it?

I changed fuse on 17, it was blown, replaced it. And stuff still doesn't work. Anyone have any other ideas what it could be???

Hi I have a 2004 mercury mountaineer , I need to know if the upper bal joint can be removed without taking the control arm off

The car shut itself off without any warning on an intersection after continuous high revving with a stuck gear. Struggled to start but when it did a loud squealing sound occurred and shut off again. I pressed the fuel reset switch and it started but the engine ran different and would not move at all. After a week a loud knocking/rattling sound occurred after starting and still won't accelerate. (It also did have a transmission problem with gear 2) Could it be that, time chain cassette, worn engine or what?

the rear lights do not turn off
even if i turn the car off and no key in the egnition

my mercury started with a check engine light then went to abs and then brake on dashboard then they would trigger the engine failsafe mode then the abs and brake light would go off we replaced throttle actuator evg valve and abs sensor but now its bringing up the abs and brake lights again with other codes what could be goin on with my car i dont want to spend thousands on stuff thats not wrong
