#934 of 1701 Rear Differential Assembly
Oct 17, 2006 (10:22 am)
I've had my 2005 Chevy Equinox AWD for 1 1/2 years. I chose it as my company car (company makes car payments for me). Pretty good deal, and I loved the vehicle until about a week ago. I have 68k miles, a lot for the age of the vehicle, but I drive a lot for the job. Recently, I noticed a grinding noise when I would make sharp turns. Didn't happen all the time, but enough to make me take it to the dealership. I was told that a pump was going bad and was quoted $2400 to repair. Apparently, GM just doesn't make the pump, you have to purchase the entire rear differential assembly. What a crock! The dealer told me that he's getting on average 20 Equinoxes a week with the same problem. Can GM say recall??? Now I'm waiting on my company to see what part if any they're going to cover on this repair. In the meantime, I have an Equinox sitting in my driveway that is useless. I am done with GM after this.

confusion. it grinds when making turns and a pump needs to be replaced (power steering pump?), but then you're mentioning a rear differential.

By the way... there is no pump nor belt for the steering and there is no power steering in the nox. It's a electric steering. A brand new concept in lots of G.M. cars these days.

I'm as confused as you (user 777) about this pump thing. I can't figure out where there could be a pump in the back of the Nox and why G.M. wouldn't manufacture all the replacement parts for their product. The only pump I ever saw in the rear of a vehicule was a "air pump" on a Venture (van). It controlled the Automatic Level Control. Otherwise, no pumps there. I'm curious about this and would like to know more. Could the owner of this Nox reply after the repairs are done.

right. i was thinking maybe the owner was being taken for a ride not on the map. i didn't know that GM used electronic stearing in the NOx. i suppose there's got to be a motor or hydraulic actuator somewhere to move the wheels from side to side. maybe the problem is there.

Electronic Power Steering
Electric power assisted steering (EPS) is designed to use an electric motor to provide directional control to the driver of a vehicle. Most EPS systems have variable assist, which allows for more assistance as the speed of a vehicle decreases and less assistance from the system during high-speed situations. This functionality requires a delicate balance of power and control that has only been available to manufacturers in recent years. The EPS system is replacing the hydraulic steering system and is destined to soon become mainstream among automotive manufacturers.

I haven't gotten the repair done yet. I have a third appt with another dealership on Friday. As for clarification, all I can say is that I was told there was a pump in the RDA that was going bad. Since the Nox is a new vehicle, GM doesn't make the individual part yet. I wasn't told what the name of the pump was, but was given a part #15224698. The part costs about $1900 and with labor the total was $2400. I was told that this was a very common problem in the Equinoxes along with the Buick Rendezvous and Pontiac Torrents (apparently they all use the same parts). I will post again on Friday when I receive another diagnosis and estimate.
#942 of 1701 Update RDA
Oct 27, 2006 (6:22 am)
I received better news today. Apparently, it's the clutch package in the RDA. They can fix the part without having to replace the entire rear differential assembly. The estimate was $958...a lot better than $2400! Still more than I wanted to spend, and more than the Nox is worth. Hopefully, I won't have any more problems.

Thanks for the update. Yes the clutch package is probably the problem. You're right $958 is better than $2400 but still it hurts. Mine is a 2005 to and I plan to keep it till 2009. God help me. I like my Nox but sometimes I wonder, it gives me a funny feeling. Good luck and thanks again for the update.
