Help ! vibration & 'clock clock' noise !

[RS13]

I'm driving a '91 S13. I've just changed & done the following;

a) all 4 shock-absorbers (stock)
b) front left lower-arm (because it was damaged)
c) both front T/C-rod bushings (stock)
d) 4 new tires
e) front 2 rotors (stock)
f) off-wheel balancing
g) on-wheel hi-speed balancing (front wheels) &
h) computerised alignment


However, I can still feel slight vibration thru' the steering wheel (at abt. 50~60 mph) , and also i can still hear 'clock clock' sound coming from the front right suspension when going over undulations.

What else can i do to solve the above problems ? Getting quite frustrated with them (after spending so much $$$<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'> &nbsp;??

Check your ball joints and axles.

As far as the vibration goes, has the car ever been in an accident?

[camppain]

the vibration at that speed is your tires being out of balanced. as for the clunking does your mufler have a cat bracket? are all the hangers in?

now since youve done your balance did they check your hub for run out? see if your bearing had play in it? your axle can have to much play also. at work i had one that had the same problem i checked the balance of the wheels and they zero'ed out. so i tightned the rotors down without the wheels and had someone bring it up to the speed it was felt at (70 mph in this case) sure enough the right side hub was moving way to much the bearing had no play in it but y0ou could also see the lateral movement of the axle.

my case was on a 01 sentra. if the shop is competent enoough they should be able to solve it.

also your driveshaft could have axial play or can be out of balance.

or your tierods can also have to much play. again go to a competant shop that wont shotgun and make yuou poay out your ass.

when it comes down to it no one can diagnose a susp problem like this over the net unless driving the vehicle and taking a look at it

Yea.... &nbsp;usually, if your tires them selves are out of balance,
they will give you a shake or vibration in the wheel ...
roughly at about 35 - 40 it will start.

If it is happening at over 45 ... then usually it from the
actual car being out of alignment ... from lets say, an accident. &nbsp;However, could be something real basic.

Did you try rotating the tires? &nbsp;See if you get less from the
back wheels.... could be just a bent rim.

Good Luck.

The mechanic has checked the rims and all are fine. I suspect the springs to be the culprit for both the vibration and 'knocking' sound. Can the front stock absorbers be fitted with any springs bought off-the-shelf ? or must I do some 'mathematical' calculation ?
