VitaminZ Posted May 18, 2015 Share Posted May 18, 2015 (edited) Ok so anytime i make left turns in low speed and change gear from 1st to second whilst turning I get a clunk coming from the right rear end . Only happens when turning left and only if I change gears . I have checked all bolts under there and all are torqued, I recently changed out all my bushings so I know they are all good . I have installed a Subaru R180 diff which has a 2way Cusco LSD in it . And I am running the beta motorsports stub axles . From the video below you can see I can move the stub axle at the diff outward with very little effort . I am guessing this is causing the clunk since I cannot move the left side ? Should there be this much play in and out coming from the axle yoke ? Couple questions , are both Axles the same length and could this be a bad u joint ? Could I have a worn or broken C clip ? I know its in there since i feel resistance when pushing the stub axle inward until is passes the c clip and seats in the groove on the stub axle. any ideas on this before I start taking everything apart would be great , thanks !!

NewZed Posted May 18, 2015 Share Posted May 18, 2015 Does the car jerk when it clunks? Is it loud? Are you turning fast or turning slow? Are you accelerating rapidly while shifting or slowly? It never clunks unless you're shifting from 1st to 2nd? 3rd to 4th is silent? What are you going to look for when you take it apart? You checked "all the bolts under there" but did you check the right strut bolts and gland nut? Did you check the hub? The axles are the same length but the distance from the diff to the hub is different. Quote Link to comment Share on other sites More sharing options...
VitaminZ Posted May 18, 2015 Author Share Posted May 18, 2015 i feel something is moving outward toward the wheel when I turn left and change gears ,1st to second it happens on initial take off at low speed and the clunk is loud enough for me to hear it yes . I haven't really been going around corners that fast on the street to change from 3rd to 4th . Yes I have checked the strut bolts and gland nut . I have not checked the hub.

NewZed Posted May 18, 2015 Share Posted May 18, 2015 Were it mine I would put the rear up on jackstands and shake the crap out of both wheels by hand, up, down and sideways, along with various other tests of hub or strut looseness. Check the gland nut. Loosen the top shaft nut and see if you can pull the shock body up and down inside the strut tube. Stuff like that. Seems like the stub axle would stay out if it came out, especially with all of that excess room. You might be focused on it because it's the only loose part you can find.

VitaminZ Posted May 18, 2015 Author Share Posted May 18, 2015 Yeh I've done that but couldn't find anything loose . You're right if that stub axle came out on its own whilst turning it should stay out . I think I'm going to have to check the strut assembly again . Thanks for the insight .

NewZed Posted May 18, 2015 Share Posted May 18, 2015 If the wheel is hanging on the strut when the car is in the air, the shock body will be pulled up against the top of the gland nut. So you'd have to check for shock body looseness with the car's weight on the springs. Just a thought. Clunk sources are hard to find. Maybe it's the nature of the Cusco diff.

VitaminZ Posted May 18, 2015 Author Share Posted May 18, 2015 Well I've been doing some reading on the Cusco LSD experiences and apparently many other users get this clunk from them . I'm going to change the oil to specific cusco LSD oil which seems cure it a bit and see what happens .
