I was wondering if the thumping sound i hear while driving could be becuase of worn out cv axles? Sounds like a flat tire going down the road. The alignment is fine had that checked. And there is no pulsating in my brake pedal so i know it is not the brakes rubbing on the rotors.
Any suggestions?

 

Tires......

 

Tires are brand new just had them put on. No wobble in the steering wheel so that isn't it either.

 

Turn down your bass!

 

I either have the same or very similar problem. So I am just hoping on the thread. I have a new axle (new from napa) on the driver side (side the noise is coming from). The noise happens once a revolution of the wheel, so as you go faster the noise becomes more continuous. I can feel the thumping in the floorboard, it is not super hard thumping but it is annoying. Is this the same problem you have? I cannot see any evidence of any moving parts hitting anything. Make sure your wheel lugs are tight before you go any further.

 

My car does that too. I thought it was un balanced tires but its not.I cant figure it out because my cv boots are new. I just live with it. Until something starts making noise or brakes im not going to throw money at it.

 

could be the strut bearing or the tower making noise,
had this problems put tokico's on it and replaced that bearing
its all good now

 

Did the thump start after the new tires were put on?
Could have a defective tire ya know.....

 

Sounds like a worn inner CV. Or maybe wheel bearing? I'd eliminate the CV joint by replacing the axle first. Does the thumping get worse when the front end is loaded, i.e. braking semi-hard?

 

in my case the wheel bearings feel fine, I cannot get any play when pushing and pulling on the wheels. As for strut mounts I am getting this nosie while the car is rolling, I thought that the strut mounts make noise when you turn the wheel and they pop from binding up. Also my noise seems to only happen under the weight of the car. I put the front end of the car on jackstands. Once the car was up I started it and put it in gear (the wheels were spinning wile off the ground), and got out to see if I could determine anything, and I was not getting any noise. So with my problem, the weight of the car is a factor too.

 

I have a feeling it's the inner CV that's worn.

 

How can you check that? I pulled my axle last night and did not see any signs of abnormal wear. This axle is new from napa (not rebuilt), and it has about 1-2k on it. One other thing I was thinking it could be is a tire. This car did sit for about four months before I bought it, maybe a flat spot in a tire (that's probably not it, but I am just throwing it out). Also would a wear indicator on the tire make that kind of noise? My tires are almost down to the indicators, the strip of rubber that run perpendicular to the rest of the tread.

I also checked my brake pads last night to make sure I did not have a rock stuck in them (a shot in the dark), nothing was there. I do not think I have a warped roters because the car brakes fairly smooth, and I do not get any push back on the pedal.

 

Check your balljoints.

 

make sure the wheel sits FLAT agains the rotor and that all the lug nuts are tight.

even tho they are new tires it might cause problem still. Jack up each corner, spin the wheel and make sure there`s no bump.

 

The fact that it's "new" makes no guarantees about the inner joints not being rebuilt. Even raxles axles have rebuilt inner joints. They only use new OUTER joints. It might just be a defective rebuild.

 

Your tires are shot, replace them and I bet your noise goes away.

 

I have brand new tires in the garage just waiting to go on the car. I was trying to hold off on them until I got this problem fixed but I may go ahead and put them on. Also I know I could use some ball joints, but I do not know why they would cause a thumping while driving. Also the alignment on my car is off, but again I do not think this would cause thumping.

 

... i fur lowered common problem is the spring contact.... put a sturdy rubber house around teh srping between coils and it should go away...

 

Im sorry, I do not know what you typed

 

flatspotted or out of round tires is my guess

 

Thanks for telling me about the new car BROTHER!!! Betchu I'm still faster

 

hehe...just got it yesterday....4th gen is like an old man waiting to croak now...lol


possibly...but i still got the big V8 in my stable...that'll give you a nice romping....
all set for you trip ? make sure you dont drive in the snow...

 

Is the 4th that bad right now? Don't get rid of it, that was like you're baby! Congrats on the car, pm me the specs, price etc I'll be careful, can't wait to get back and see everyone, and get settled back down.

 

To be honest its those crappy NAPA AXLES, I have replace three right axles with NAPA being under warrenty to, they give a lil vibration on the highway or slight turn on the highway to the left after like 1500 -2000 miles, almost as if there loose, I'm lowered. But my friend Chris, MAXPOWERX has napa axles and the same thing is happening to his car and he isn't lowered. So go figure lots of other here also have had those same issues with napa axles there rebuilt pieces of crap there arent new. Well my driver side has just been torn so I'm going to buy a raxle...

 

well common prob with 4th gen is that when lowered you hear noise liek tumps etc. now that occurs wehn going over bumps and not even huge bumps might i add.. you can hear it in a seiers of smaller dents etc...

it happens when the 4th gen is lowered.. the lowered springs make contact between coils... most time top 2 coils with space.. if u can lift u car up on alift.. you can see where the contact is made cause there will be visible wear on ur spring... u will see it... any how put some type of rubber hose.. verys stirdy but not thick one aroudn that coil with most beating.. cut the hose in a sprial candy cane design that way u can slip it onto the spring and not worry about it comming of.. it helps alot..

this is common in front by the way.. also if you hear alot of noise in rear might be mount bushing..

 

His problem has nothing to do with what you're describing. What he's talking about is a rythmic thumping that becomes more frequent as speed goes up and vice versa. It's either the tires, axles, or wheel bearings. Did you bother to read what the symptoms of his issue was?? If you did you would know how far off base you are.

 

Damn, you beat me to it. I only clicked on this thread to see if anyone replied that. That was my first instinct. Anyway, for the bass.

 

did you ever get a decent axle from napa? The reason I ask is because the guy told me they are trying to do away with their rebuilt axles because they have been giving them so many problems. And the only one he had in stock that day was a new one which was $120 most of the rebuilt ones are like 60 or 70 plus core I thought. I am leaning more and more toward the axle but I would like to just get a new napa one if that is the problem since it is warrentied....I would rather not loose that 120.

 

.........

 

if its the cv joint it will knock when you turn

 

no, it does not do the traditional axle clicking when you turn. Its the same when turning or going straight.

 

Check the carrier bearing on the RH drive stub shaft between the transmission and the inner CV joint. Mine is bad and is making that noise. (see New Diagnosis for Rotable noise posted here 12/10)

 

NOT ALWAYS THATS WHEN ITS LOOSES GREESE> ThE PROBLEM WITH NAPA REBUILT IS THEY DONT REBUILD SOME OF THE PARTS >>>><<<<<
