2000 Ford Focus SE makes a loud pop in left front tire area when making left hand turns. I did the CV Joint test by doing a constant left hand turn in a large parking lot, and it only popped once upon the initial turn. Suspect strut/shock/spring assembly. Maybe spring broken. Any other other suggestions? Oh, the left front tire seems to wear on the outsides near the tire wall, but only the left front tire.

possible cv joint failure

Sounds like it could be the CV joints, drive the car in reverse for a little and put steering on full lock, the noise will be a crunching sound coming from the front, if so then ist definitely the CV joint(constant velocity) joint, hope this helps

you need to replace the cv joint (constant velocity) you can get them remanufactured at auto parts store at a fair price

Clicking might be your damaged axle, check the cv axle.

Sounds like the CV (constant velocity) axle shaft joint is bad. I would advise to get it checked as soon as possible. Dangerous to drive it like that. CV could break.

Common or not,you need to find the issue and repair.
You must have missed a bad CV Joint.

Loud popping/grinding most noticeably heard when turning is normally a sign of a bad CV joint. Look under the van where the axle half-shafts come out of the transaxle and connect to the backside of the wheel assembly. Are the rubber boots on the axles torn or missing?
If you hear the popping only in left turns, your right CV joint is bad, If you hear the popping only in right turns, your left CV joint is bad.

I recently had the same problem, it ended up being the front stabilizers and the drive shaft.

ck the CV boot. if its broken you need a new cv axle, if its ok, jack up the car so both wheels are off the ground. either put the car in drive or just manually spin each front wheel while gripping the coil spring for the front strut. if you feel any (roughness) at all, that wheel bearing is bad. it should be smooth. if you have a bad one you will know it by this method. Even good mechanics sometimes replace the wrong bearing, but this 100% works every time.

Check for recalls, I had the front springs replaced for free on my 01-SE
