clicking noise, but not in turns
Posted 21 December 2003 - 07:41 PM
Got a minor problem that I am having a hard time diagnosing. I have what sounds like a rhythmic clicking CV joint that carries on intermittently when driving along at certain speeds....usually 35mph or more. it is coming from the front passenger side. And it typically happens when I am driving straight (i.e., not in turns). Replaced both axles about a year ago and checked the boots and everything is fine with them. There is no clicking at all whatsoever in turns....it is only when I am at cruising speeds. Although slightly turning the steering wheel to the left or right when on the highway (an inch or so) will sometimes change the pitch of the noise. And it will also make teh noise depending on the slope of the road...a slight slope to the right will usually aggravate it and make it show up. Also, when it is making this clicking noise, if i tap the brakes it stops and as soon as I let off the brakes it usually comes back. But as soon as I let off teh brakes it will start up again. I have had CV joint problems in the past and know what it sounds like. This sounds just like clicking CV joints. But there is no damage to the axles or boots at all. And I would think if it was a bad joint it would make noise in hard turns when accelerating. And it does not do that. I have checked the brakes and everything looks fine with them and everything is tight. Could this be a wheel bearing, differential problem, inner CV joint or something else? Any help is appreciated. Thanks!

Jim usually gets good deals on parts, and i, alleyboy(jon from columbus), and even tom from michigan meet there often. hopefully some day we can meet!
anyway, i would suggest removing the cotter pin and re-tightening the axle nut. i say so because you said it was serviced before. the noise you sedcribes sounds like the rotor hitting the caliper bracket. this will happen if the axle is loose or has bead threads. i had this on 2 occasions.
i had a wheel bearing noise once, it would be aggravated on by the crown of the road at cruise speed, but was not so bad on the left lane on a 4 lane hiway. also, the noise was there when i hit the brake.
if the inner axle goes bad, it will want to pull the wheel to that side, jerk, jerk, jerk, in an oscillating pattern according to speed.
i would put my money on the axle nut or its threads. the axle presses thru the bearing, the rotor seats against the outer bearing, and the nut holds it all together. if there was not enough torque on the nut when the axle was last serviced, just the slightest amount of play will make noises like you sescribe.
i believe the axle nut torque is 145 lbs. (can anyone back me up?)
i would suggest to remove the axle nuts and inspect the thread, and re-torque them to rule that problem out first, then go from there

Anyway, I think I will take the cotter pin out and check out those threads and then retighten it. I don't have a torque wrench though. Is there a possibility of doing damage by overtightening it? Or is that hard to do? Thanks.

do what i do. if the nut is off, tughten it down snug with a ratchet by hand. the use the breaker bar to snug it a little.
then put one full quarter turn on the breaker bar. that will be plento of yourque.
the idea is to have the axle drawn all the way thru the bearing when beig tightened the first time.
