Paul 987 Posted October 9, 2023 Share Posted October 9, 2023 Apart from being sideways that is. Sorry tried changing orientation before upload.I recently noticed that the off side rear ARB drop link is at a jaunty angle and the ARB arm seems bent inward to the centre of the car. Compared to the near side. See below.Although I'd not noticed before and I've had no incidents in my ownership since June. (Ok the rear may have taken off on some particularly vicious ridges on the A23 round Crawley). It could have been like this since i got it.Also, a less than scientific check with a spirit level on the roll bar (with me in the car) show the Off Side is high. Garage floor is pretty level2009 - S3 Sigma.I'd appreciate thoughts on whether it's just the ARB has suffered previous damage or if something else is going on.Cheers Link to comment Share on other sites More sharing options...

John Vine Posted October 9, 2023 Share Posted October 9, 2023 I think you're missing this hex extension piece: CC's P/N is 72141, but how they can charge that much is a mystery!JV Link to comment Share on other sites More sharing options...

ChrisC Posted October 9, 2023 Share Posted October 9, 2023 The hex extension was dropped in later builds, so they are not needed. How central is your dedion tube, measured from the chassis rail? It should be within a mm. If it's not central then the spacing of the a frame could be out. Link to comment Share on other sites More sharing options...
John Vine Posted October 10, 2023 Share Posted October 10, 2023 #6 Do you happen to know in which year the hex extension was dropped? My 2008 car has one, and the OP's car is only one year younger.JV Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted October 10, 2023 Member Share Posted October 10, 2023 The photograph in #3 was in the Assembly Guide up to the last text-rich version in 2016.AIUI that doesn't mean that the factory was recommending it.Jonathan Link to comment Share on other sites More sharing options...
Tiddy7 Posted October 10, 2023 Share Posted October 10, 2023 Just bend the ends of the anti-roll bar out until the two sides are the same. The construction of the bar is so crude that +/-25mm tolerances are not unusual Link to comment Share on other sites More sharing options...
ChrisC Posted October 10, 2023 Share Posted October 10, 2023 The hex extension wasn't part of my Oct 2015 360 or my Sep 2019 420 kits. Link to comment Share on other sites More sharing options...
John Vine Posted October 10, 2023 Share Posted October 10, 2023 #10 That's interesting. Does your O/S ARB drop-link look like the OP's or is it vertical(ish)? If the latter, was the mounting bracket different in some way, or did you simply attach the lower end of the drop-link from the outboard side of the ARB arm?JV Link to comment Share on other sites More sharing options...
John Vine Posted October 10, 2023 Share Posted October 10, 2023 Actually, looking at the OP's O/S photo again, the bottom end of the drop-link is already attached from the outboard side, so is different from my photo. That suggests that his problem is simply due to a bent ARB arm.JV Link to comment Share on other sites More sharing options...
JrPorkchop Posted October 10, 2023 Share Posted October 10, 2023 Not that I notice detail or anything, but the picture from the build manual shows a hex head bolt -> axle -> nutspacer -> ARB -> Link. The bolts are different on each side in OPs picture, the left hand side looks like the nutspacer and the right hand side is a nyloc nut. The nyloc nut looks to be used to attach the ARB ear to the link. Also every ARB link (which is 4 :) ) I've done has used nyloc or some form of anti-unwind on both ends.Or John's suggestion that the ARB ears being bent sound about right, should be easy to identify.

Paul 987 Posted October 11, 2023 Author Share Posted October 11, 2023 Thanks All for input.Apologies for not responding, didn't seem to get notifications.It's an ex academy car and was upgraded to super sport so not standard. I note the drop link top bolt arrangement is different to the Guide.In the end I took the easy way out and popped into PGM as they are only 20 mins away.The ARB blade was bent inward, presumably some previous trauma. No other obvious indications of cause though.#6 - I'll look into that thanks and as time allows get a full geo done. Link to comment Share on other sites More sharing options...
Area Representative Geoff Brown Posted October 11, 2023 Area Representative Share Posted October 11, 2023 Either the blade of the ARB is bent in or the whole o/side arm is. If anything else was offset you would know from the handling manners ! Link to comment Share on other sites More sharing options...
John Vine Posted October 11, 2023 Share Posted October 11, 2023 #14 Thanks for the feedback and diagnosis. I've no doubt PGM will sort things out.JV Link to comment Share on other sites More sharing options...
