This is my second cobra and, ironically enough, I've only recently heard about needing to tighten the rear axle nut and none of the cobra guys I hang out with knew they needed to tighten this thing as well, let alone how often.
My car started to wonder a little a couple weeks ago on the freeway and it kept getting worse. I thought the car was just tramlining so I didn't give it much notice. Well, when I searched the word "tramlining" I read about the rear axle nut needing to be tightened with every oil change. I got the car up last night and the rear wheels move a lot in when shaking from the 12 and 6 position. There are A LOT of threads about this from 3-4 years ago, but nothing recent. I don't own a 36mm socket or a torque wrench that can torque to 250 ft/lbs, but that will be fixed today and I'm hoping that I don't need to replace the hub and the bearing, but given that this has been going on with a lot less severity for the last couple MONTHS, I think I'm probably going to have to.
For the suspension gurus...when should I be checking/replacing components on my IRS? When I owned my M3, it was pretty common knowledge that I needed to replace the rear trailing arm bushings's at XX,XXX amount of miles and the rest of the bushings in the rear at XX,XXX amount of miles and same with the front trailing arm bushings at another interval. They were available from aftermarket venders as well as dealers in the stock rubber or poly (which I wouldn't touch).
So now I know that the axle nut needs to be tightened at every oil change, but when does the rubber need to be replaced in the IRS? I know, I know about the FTBR kit and I have every intention of installation, but not everyone wants a higher NVH, especially on a DD
Is there anything else on the IRS I should be checking on a regular basis? Any help would be awesome :beer:
