rgallant Posted July 4, 2012 Share Posted July 4, 2012 Hi All, Just to start off my trailing arms are only about a year old, may be 5000K, but recently I have noticed a bit of a back end shimmy when I come off the gas at anything over 60K (40mph) and under 100k (60mph). Just to be clear this only occurs when I come off the gas. The shimmy is momentary and seems to be coming from the rear, just a few seconds but a little disconcerting. I just replaced the rear shocks and the left rear upper bushing was was seized, need heating to even turn it. Cut the rubber out, it was badly torn and heated the bushing to remove it (a good 20 minutes of cursing). My question is could that have tanked one of my trailing arms, they seem pretty tight none of them seems to have significant play Or could the panhard bar cause the same issue ? Any other suggestions ? Any other good tests to check out the trailing arms. Link to comment Share on other sites More sharing options...
Der_Vier Posted July 4, 2012 Share Posted July 4, 2012 In all seriousness, my novice and amatuer understanding of the suspension system says that you may have done something to a trailing arm bushing, panhard or sway bar. If money and time allows, why not replace all the bushings back there? Link to comment Share on other sites More sharing options...
rgallant Posted July 4, 2012 Author Share Posted July 4, 2012 Mostly because I would rather not replace 3 good arms if only one is bad, at 80 bucks an arm it is a waste of money, $240.00. And I really don't need 3 spares. Link to comment Share on other sites More sharing options...
linkinpark Posted July 5, 2012 Share Posted July 5, 2012 Very common problem. I would get some replacements for the panhard. And when you say the left rear upper bushing your talking about your shocks right? Not one of your control arms? Link to comment Share on other sites More sharing options...
rgallant Posted July 5, 2012 Author Share Posted July 5, 2012 Yup frozen shock bushing not control arms Link to comment Share on other sites More sharing options...
madhornet Posted July 5, 2012 Share Posted July 5, 2012 my pathy just started doing it i put in the lower trail arm bushing because it would do the death wobble at around 70km or 45mph but there was no shimmy now that i can do 140km with no wobble all of a sudden after 2 months it is doing that shimmy thing weird Link to comment Share on other sites More sharing options...
rgallant Posted July 5, 2012 Author Share Posted July 5, 2012 I will let you know what I figure out. Link to comment Share on other sites More sharing options...
linkinpark Posted July 5, 2012 Share Posted July 5, 2012 Mine did it a long time ago. Replaced all the bushing with Poly ones and drives like a champ now. Link to comment Share on other sites More sharing options...
ennacac Posted July 8, 2012 Share Posted July 8, 2012 Mine did that also, so I replaced all the bushings in the control arms and the panhard rod which solved the problem completely. Around $110 for all the bushings (OEM) and just the time to press the old ones out and press the new ones in. Tom Link to comment Share on other sites More sharing options...
rgallant Posted July 12, 2012 Author Share Posted July 12, 2012 Well it has my Mechanic confused, the R50 goes in on Friday for a complete check. But his experience is the same as mine it seems like a failing trailing arm when it happens but it is very inconsistent. So it happens one time and not the next 5. I don't have time right now to pull them off and inspect so it he going to do a front to back check of all the bushing etc. Will report back on Friday.

rgallant Posted July 13, 2012 Author Share Posted July 13, 2012 Well there you go, less than 1 year and the bushings on all 4 arms have separated. Anyone have any problems with a machine shop pressing the old bushings out and the new in. I am going for warranty replacement but not holding my breath. So I am thinking poly all round.
