I have a 2005 Mercury Mountaineer that has 97k miles on it. The front drivers side wheel clicks when driving straight, you can also feel it in the steering wheel. I have been told that the CV joint may need to be replaced. Is this common and is it expensive to fix. Can you replace just one side and not the other or all four?
Is it dangerous to drive with it in this condition?
It sound's like the cv joint is bad are the boots torn on the driver's side?You only have to replace the bad cv joint's you can replace the bad one on that side or both the inner and outer joint's. Or you can get a reman axle assembly. If you can feel it in the steering wheel you need to change it right away. Does the noise get worse when you turn left or right?It is dangerous to drive if it's as bad as so say it is the axle could break loose. The front complete axle's are only 60. Let me know what the answer's to my questions are.

You can feel it in the steering wheel and actually hear it to some extent. It started out as a small noise about a week ago and has now progressed to louder and being more apparent. You do hear it a little when turning, its more apparent when driving straight though. I just checked both the drivers side as well as the passengers side, none of the boots are torn or damaged in any way. It sounds like I may be better off replacing the complete axle if I'm understanding this correctly. As I looked up the description of the CV joint and how it functions, it looks as though its something that could break while driving and cause more damage due to waiting.

Yes that is what I was telling you about if the axle broke it could be dangerous. So it's a clicking and not a roaring noise?I just want to rule out a possible bad wheel bearing.

Definitly a clicking noise, I have listened outside to see if there was any sort of noise that could be heard and theres none. Its as if there was a flat spot causing the noise when the wheel turns, which is what I assume I'm feeling and hearing inside. I can pick up the CV joint and have a friend whose a mechanic replace it. How long does it take to replace, meaning how long will the truck be out of commision, it looks fairly simple.

It only says 1hr labor to replace the whole axle so what I would do is have your friend put the car on his lift and have all the wheels off the ground and spin them in gear to listen and make sure it's that axle making the noise and not something else. Let me know what you find and how it goes.

I just called and he is going to look at it tomorrow afternoon sometime. From the sounds of it, aside from taking it to him I'm thinking its not a good idea to go far with it tomorrow during the day. I'll have him check all the wheels to make sure its the axle/CV joint. I appreciate the help and will update you in a day or so. Makes me feel better that I have an unbiased answer or suggested direction to look. Thank you.

The best way to know which cv it is, inspect which boot that has split and you will see evidence of greese being slinged around the inside of the wheel, or the area next to the transmission diff output seals. It is better to replace the axle, then the cv since it requires more tools and a parts cleaning tray and the EXPERIENCE in taking apart the cv joint, greasing it, then putting it together.

None of the boots are torn, or appear to be, but I'll double check that. From the looks of the details I found I think your right the whole axle will be easier. Hopefully by tomorrow afternoon it will be fixed. I prefer not to drive my kids around with it in this shape. I'll update you tomorrow on the fix. Thanks for all the help.

Cv click is anoying at best. Can you put it in drive on jacks and hear the noise? Make sure the car is also chocked an emergency engaged.
Another mechanics trick "I found this out from a mechanics only forum" put your hand on the strut spring engine off, tranmission in nutural, then rotate the tire. If you "feel" vibrations ie, roughness, it is most likly wheel berring. Also, grab tire at top and botom and move in and out same side to side, and pull on both side and out.
CV joint click is very distinct in that it is a pattern like click. Click. Click. Click. Click. To me it sounds more like a POP. POP sound. It happens most often taking sharp left or right turns.
