After coming off lift ass-end has issue
 

After taking the X off the lift I notice that the ass-end feels like it breaks traction for a second when in a shallow curve and over a small bump (no tire noise). The whole rear end has been rebuilt within the last year and all parts are still tight and unworn.

I'm leaning towards the idea that it may be due to an airbag being off center, loose or something along those lines.

Thoughts? Ideas? Parts you'd love to give away:stickpoke:[emoji38]

Did whole rear end include sub frame bushings? Especially when under power, if I hit a bump the power train gets slack for a moment when the rear end gets light out would be a very similar sensation to what you described. I have pretty worn bushings so I can hear a thud also when the drive train tightens back up and torques the subframe back

Yeah and everything is still torqued to spec. Do think I should try retorquing everything while it's on the ground and on sprung weight?

Maybe you are just getting airborne. If you actually lose traction you will get a DSC flash on the dash. Do you get a yaw motion? What makes you say lose traction? Under power does DSC engage? You might get a bit of yaw feeling from a bump in a corner just from the sprung weight getting bounced in the air and letting the car pitch at the same time.

To be clear the "yeah" was subframe bushings replaced?

Sorry. The yeah was about the subframe bushings being redone also. It doesn't actually lose traction but it sure feels like it and it's almost like the ass end fishtails an ungodly amount but since I'm not expecting it, that may just be my perception. The DSC doesn't light up at all and the only codes in my foxwell and the mechanics ista-d show my O2 heater on bank 2 and O2 sensor on bank 1. Although with a pregnant wife that has a bladder the size of a walnut I'm sure my pads lifespan is down by 50% but that will be my next full inspection on 03 Feb 2019.

So PUSH it a little and break traction to learn where that point is. If only you can find a road with some sand on it. Get the DSC to kick on to correct a yaw then turn off DSC and see what happens

Of course do this where a spin or slide won't put you into oncoming traffic or a guard rail. In the USA we practice on snow in parking lots.

(I turned off DSC on a large radius turn on snow and instantly ended up sideways!)

LoL

Finding a road with sand.... Not a problem.

DCS engaged almost instantly and couldn't get it to be too squirrelly and then driving on it seemed more like the body was sliding.
:dunno:
