No limited slip. Sounds more like mounts to me.

Say WHAT ?
Sorry. Always willing to try and help. But I can't make any sense out of that post.

Cv axles are toast, while you’re at it replace the hubs.

i have a 2007 chevy hhr 2.2 auto trans when i put it reverse or drive it will jerk and make a popping sound also when i am driving the car vibrates at about 55 mph and if i let off gas it will stop vibrating's could it be a bad cvc axle are bad splines on either the cvc axle or bad splines were it goes into trans?

When you put it in gear, it jerks and makes a popping sound. Is this before the vehicle starts moving, i.e. with the brake still applied?

weberr24

Yes before vehicle starts moving and my foot still on the brake

RJ_RS_SS_350

Yes, that does sound like it's the CV axles.

i took out driver side cvc axle and cranked it up and put in in gear with foot on brake and it did not pop are jerk so it was the cvc axle bad correct? The boots were intact no tears and had plenty of grease but that don,t mean it was good correct?
