xbeerd Posted May 22, 2012 Share Posted May 22, 2012 (edited) ok, so i did search for this already, couldnt find anything. when i accellerate i hear a clunk sound one time and then wont hear it again until i slow to a stop, hit the gas again and it'll go again. if i take off pretty slow, it wont do it. its not a click like a CV, i have replaced the bushings on the radius rod and still get it. sounds a little different with the new bushing. im pretty sure its not the upper strut bushing as i've had 2 different ones in there. and happens with or with out the lift Could it be worn tranny mounts possibly? im not sure how 'spongy' they are when worn? they feel a bit spongy, and im sure are original from 1989 with the trans. this is a 92 loyale. anyone have this before? any ideas????

xbeerd Posted May 22, 2012 Author Share Posted May 22, 2012 i think i might have accidently deleted some words there. lol.. i have tried different struts in there. (not just the upper strut busings) now. being that these struts were both either from 1992 or 1987, they could both be bad, but im doubting thats the case.

Storydude1 Posted May 22, 2012 Share Posted May 22, 2012 Sounds inertia related. Like a loose wheel or rotor getting thrown back and forth. Ball joints tight? Quote Link to comment Share on other sites More sharing options...
Chevydog89 Posted May 22, 2012 Share Posted May 22, 2012 Just posted this in another thread... I've had the same issue, so I'll give you a quick rundown. I have a 92 Loyale, it's just front wheel drive and automatic. I had to replace the front right CV shaft because it was all mangled from where the joints join at, so I did that, and all was good. Then all the sudden some slight clicking/chattering sound started coming from that front side, so I decided maybe the CV shaft just worked a little loose from driving, and I tightened it down again. Well, one night my girlfriend was driving it and she couldn't move all the sudden and the shaft was just free spinning in the hub. It turns out the hub was bad and had to be replaced. I guess it wasn't staying tight with the shaft and it was just worn out. The shaft and splines were still good though. What the chattering sound was, the CV shaft would loosen up, then my rotor on that side would be loose, and it was actually chattering back and forth, when I was going down the road. So, you may pop off that tire, and see if the CV shaft is a little loose, and if that front rotor is too. If so, it could possibly be the hub going bad. It cost me $300 to get it done at a shop... which was a very good price for something that turned into a headache. Quote Link to comment Share on other sites More sharing options...
xbeerd Posted May 22, 2012 Author Share Posted May 22, 2012 yeah as far as i can tell. i tried to shake things around a bit, i couldnt find my pry bar to try to pry it around. but yeah, seems like its due to the accelleration that whatever it is shifts. unfortunately i cant seem to find anything that will shift when the car is still, especially if i jack it up, with the lift its pretty tight. when all extended.

TheLoyale Posted May 22, 2012 Share Posted May 22, 2012 Control arm bushings or Rear diff top mount bushing? Front Sway bar? Clunk or a pop? Did it do it before the EJ swap? (More torque) How are the Top hat bearings? Quote Link to comment Share on other sites More sharing options...
l75eya Posted May 22, 2012 Share Posted May 22, 2012 Check your wheel bearings out yet? Quote Link to comment Share on other sites More sharing options...
AKghandi Posted May 22, 2012 Share Posted May 22, 2012 (edited) I had this problem once my radious rod bolts were loose.. But seeing as you have replaced the bushing i would suspect you tightened them.. Another random clunk i had(i thought it was the diff snout bushing) was exhaust clunking against the body. Probably not helpful but thats my 0.02 Edited May 22, 2012 by AKghandi Quote Link to comment Share on other sites More sharing options...
Moosen Posted May 22, 2012 Share Posted May 22, 2012 Oh god the infamous clunk. can't figure mine out. Might be ponying up to buy new struts and see if that fixes it. Quote Link to comment Share on other sites More sharing options...
AKghandi Posted May 22, 2012 Share Posted May 22, 2012 Yep we have all experienced the dreaded clunk.. First thing i do when i hear a clunk is check EVERY bolt then i start pulling/ prying till i find something that looks odd or broken. If that doesnt work i get creative...once i had to work that clunk till it got so bad I'd have to be deaf and blind not to find the issue. Then i repaired accordingly. Not the best method, but when theres a gremlin sometimes you gotta get on ITS nerves till it rears its ugly little head...Plus, who here doesnt like working on their car?

86 Wonder Wedge Posted May 22, 2012 Share Posted May 22, 2012 If you bring the revs up to about 5 or 6k in first, then let off the gas (engine brake), does the sound happen again? It sounds like a lay shaft or even the trans isn't torqued down or something is shifting under load.. Quote Link to comment Share on other sites More sharing options...
Chevydog89 Posted May 22, 2012 Share Posted May 22, 2012 It could be your hub going bad man. Pop that tire off and see if you can shake that rotor back and forth. If you can, and you know that CV shaft nut is tightened down as it should be, then your hub could be bad. That was my issue. The rotor was chattering back and forth because the hub couldn't keep the CV shaft nut tight. Quote Link to comment Share on other sites More sharing options...

(More torque) How are the Top hat bearings? rear dif top mount bushing? probably not, this is definately up front. did it before the swap, top hat bearings i think are good, i've had the top hat original to the car as well as fox's 3door strut/tophat that he gave me. same result, i wouldnt expect them both bad.

xbeerd Posted May 22, 2012 Author Share Posted May 22, 2012 Check your wheel bearings out yet? that was a thought as well. i have a spare hub at my parents place, but dont want to swap it until my new tie rod ends show up as i dont think the current one will survive another beatdown. i also dont know the health of the wheel bearings in that hub.

LOL. too bad because that would have been easy. haha. lookin like i'll have to try swappin that hub and hope the wheel bearings are good in it.

It sounds like a lay shaft or even the trans isn't torqued down or something is shifting under load.. lay shaft? something is definetly shifting when power is applied. i generally cant hear it when i let off the gas. havent tried revving it out over 5k and letting off the gas tho Quote Link to comment Share on other sites More sharing options...
ivans imports Posted May 22, 2012 Share Posted May 22, 2012 check the trans strut support brace iner bolt likes to come loose and will clunk and alow the trany to move and exhaust center mount likes to break Quote Link to comment Share on other sites More sharing options...
xbeerd Posted May 22, 2012 Author Share Posted May 22, 2012 (edited) "trans strut support brace" would that be the trans mount where it mounts to the cross member? i'll double check all the tranny mounting bolts and such. unfortunately i am being stuck at work until about 10pm tonight.

Moosen Posted May 22, 2012 Share Posted May 22, 2012 can you get a video of clunk. I want to hear if it is like mine. also try putting weight in the car and seeing if it changes. Quote Link to comment Share on other sites More sharing options...

I want to hear if it is like mine. also try putting weight in the car and seeing if it changes. i'll try for some video. i think if i put some weight in the car at the rear, it would lessen as the weight has shifted back a bit. when my suspension was all stretched out after having the car jacked up, i thought i had solved the problem. then it settled... :/doh!

This would pretty obviously imply that it is either your suspension components directly or something in the front end/steering that is changed when suspension is dropped out.

Dirk Posted May 24, 2012 Share Posted May 24, 2012 I'll bet an ice cold pint of lager that its the arse end of the transmision knocking down on its crossmember. Check that rear transmision mount and the clearance. Do you have a pitch stopper? Cheers Dirk. Quote Link to comment Share on other sites More sharing options...
