Strut or CV joint???

19 posts in this topic

93 Grand Am.

When I turn to the right, either sharply or just taking a curve, I hear and feel a very slight thump, thump, thump coming from the drivers side wheel area. It's not the real loud thump thump that is normally associated with a CV joint.

I put brakes on my car the other day. While I had the wheel off I looked for something noticeable, and didn't see anything. The CV boots looked good (I realize a good boot doesn't mean the joint itself can't be bad), nothing wiggled, things looked good.

Any suggestions???

It sounds like you have already came up with the best answer yourself, sounds like a bad c/v joint to me as well!

How about a bad bearing in the hub assembly? Normally they will hum when going bad, but I have seen some that thump.

BG,

Are you sure it is not a Loud sharp tickity tickity tick? That noise has been the badge of a worn C/V joint since front wheel drives come on the road.

A thump thump thump, to me could also possibly be a tire issue.

How do the tires look? Is the inside edge worn. Run your hands down tread and see if you find some flat spots.

If this is not the case, it could be a c/v joint.

I was thinking CV joint from the get-go, but it's not the louder noise I'm used to hearing. No hum, no tick tick, the tire wear looks very even. I was hoping it was an out of balance tire so I had them balanced recently, and no weights were needed.

This is why I'm asking yous guys. I'm a shade tree mechanic not a tech. This is a dull thump thump thump that I'n not used to hearing.

BG,

Did they rotate the tires at that time? If not I would for gicks and giggles do it and see if noise goes away. Just cause tires balance out, does not rule out an internal cord issue. A big shot in the dark, but after a visual inspection, it would be one of the next steps a front end tech. would do and then test drive!

What brand of tire is it? Goodyear?

Another shot in the dark.....Does the noise change with braking? Corroded rotors could be a possibility. Sometimes when rotors get old they rust and corrode to the point that pieces that start to flake off and can cause noises.

Does the noise only happen on turns, if so how about when turing in both directions?

Only happens when I turn to the right. Whether it's a sharp turn or going through a curve. Turn to the left, no noise. Go straight, no noise. No noise when braking.

Last weekend when I did a brake job I installed new rotors on both sides. So, I know at least they are good.

Didn't rotate tires. I'll do that this evening.

Was the noise there before the brake work was done?

Could be a wheel cover.

Any noise change when accelling and turning vs coasting and turning?

While you are rotating the tires shake the wheel and check for lose wheel bearing. If it is ok, you could run the car on the jack stands (set it up safetly) and listen when the wheels are off the ground!

Noise was there before brake job. Just harder to hear with all the squeaking going on.

Accel and turn vs coast and turn, same noise. I don't think it's a wheel bearing. ( I could be wrong, tho) I tried to shake the wheels pretty hard and they don't move.

I would check the tires. Sounds like a cupped or flat spotted tire on the inside and/or outside edges. With some tires it doesn't take much to make noise.

Like stated early rotate the tires to see if there is a change.

How fast are you going when it makes the noise. I would bet that a left front wheel bearing is in your future! It has all the classic symptoms. No noise straight, gets louder when you turn right no noise when turning left.

Speed doesn't matter. Even when pulling out of my driveway the noise is there.

This evening I'll rotate tires and try to put the shakin of a lifetime on the left front again to see if I get any wiggle.

One more thing BG, does this have hubcaps/wheel covers? If it does take them off and see what happens. I just had a cavalier last night making "rubbing" noises. Turns out the wife (likely story) likes to ride up on curves and ended up pushing the wheel cover into the rim so that it was wedged out of place.

I didn't see a reply? Don't want to steal fishintechs idea but i think its important enough to at least find out/rule out.

    • LH...I repaired Shimano's for years, and this was a huge issue for the Stradics and the Sahara's, First, look at the bail and make sure that they are not out of alignment. I bet your problem is caused by one part (and it's the probable cause of both problems)..... To keep the bail from rotating on the cast (and snapping shut on you in mid-cast) there's a small friction ring inside the rotor. It looks like a heavy rubber band only it's made of heavy vinyl plastic. It's  actually called a "friction ring". When it goes bad it loosens up just enough to bind up your reel completely and the bail won't snap shut. Also check the round bail return spring with the smal 90* bend in it, that can pop out of the tiny hole (the "bent" end) and cause the bail to do literally nothing. If your bail actuator pin (your :latch") is bent/worn, that will do it, but unikey that it's worn down that much. Loosen up the bail center screws, and see if when they are loose the bail will return. If so, they may be bent/out of alignment. Takes some careful maneuvering to get them back to proper set. I love Shimao stuff, but they never did own up to this problem, as far as I know. Check those things first and let's go from there.

       
    • Look at the diagram, order the parts.   If it pops open or won't close I am still thinking the spring... Take pictures with phone or digital camera as you take it apart.  Helps to get it back together. 
    • Wrong guy there.  I don't fish in MN anymore, don't have a boat either. 
    • Clinton.     After Mn coughed up 66 million for 150 jobs in Cook, nobody from MN ought to be criticizing Indiana.  Looks like they got a heck of a deal.
    • who hasn't done something dumb like that.  I know I have!   good luck making it up to you Mother!!
    • *sigh* Kiss of death my friend............. kiss of death.   LOL
    • make / manufacturer: Eskimo
      model name / number: Mako Upgraded to an electric auger and selling my old one. Runs great and has been well taken care of. Starts on 2-3 pulls every time. I have the extension for it as well as a new set of blades that I bought but haven't needed to change yet. I also have a cabelas auger bag that it fits in.
    • the thing that trips the latch is worn or broken.    i think   will take apart and look if i set hook hard the bail rackets pops up and lets line out won't close some of time...have to do manually
