Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video we're going to show you how to replace the front wheel hub on a 2007 Pontiac G6. It's fundamentally the same operation for a 2005 through 2010, and it is the same operation for left to right side. In order to do this procedure you're going to need a jack and jack stands; 35, 19, 15, 14, 13 millimeter sockets; socket wrench and extension; a hammer; screwdriver; and a breaker bar with the pipe for extra leverage if you don't have air tools.
Use a 19 millimeter socket by hand, to remove the plastic lug nut covers. Forward while I take those off. Now, remove the wheel and tire. If you don't have air tools start with the wheel on the ground, loosen the lug nuts, then raise and secure the vehicle, and remove the wheel and tire.
You want to remove the axle nut. I'm using an impact wrench, and what you can do is, if you don't have an impact wrench, have somebody hold the brakes and use a breaker bar and a 35 millimeter socket and probably even a pipe for extra leverage to loosen it up.
By hand turn the hub assembly so that you can gain better access behind it. Use a 14 millimeter socket socket wrench and remove the two bolts that hold the caliper to the caliper bracket. I'll fast forward through removing those two 14 millimeter bolts. Pull the caliper up and off of the caliper bracket and put it up into the side. Take a screwdriver and pry the pad away from the rotor. Do that for both the inner and outer pad.
Using a 15 millimeter socket and socket wrench remove the two bolts that hold the caliper guide to the spindle assembly. I'm going to fast forward as I take out those two 15 millimeter bolts. Pull the caliper bracket up and out. Remove the brake rotor.
Make sure your axle is free from your hub. Put the hub nut on, give it a couple of wraps, watch closely the relationship of the axle to the hub and you should see it move, and then you know it's free. On the inside of the hub and spindle assembly you're going to find three bolts. Locate those too, one on the top and then two on the bottom. Use a 13 millimeters socket, socket wrench, and extension, if you need to, and remove the three bolts. I'm going to fast forward as I remove the front and top one. Then, go ahead and remove the one on the back side. Here I'm using a hammer, where I'm going to tap at the back edge of the wheel hub. Once I've got that, I'll be able to pull it out. Make sure while you're doing that that you maybe give it a little tap or two to the end of that of your axle so that that goes through, but be careful not to damage any of the threads on it. Then once you got that out go ahead and pull it out and take off your backing plate.
I've got the old part, and the new part from 1A Auto and it's a direct replacement fit. You see we put the new hub in place with the backing plate behind it and started the bolts in by hand. Now I'm going to finish tightening those bolts with my socket and socket wrench. Again, I will go ahead and fast forward through that. Now, you're going to want to reinstall the nut on the end of the axle. I'm going to go ahead and use an air gun with this and I'll fast forward.
Our brakes were fine so we're going to reinstall them. But if yours needed to be replaced go ahead and put your new rotor on. Then you can use a lug nut to keep it pressed against the hub while you finish up the brake work. I'm going to reposition the wheel so that I can get access to the back of it. Before I go ahead and put that caliper bracket back on I want to make sure that slides are well greased, so I pull them out with the boot, check to make sure that this grease on them. If there isn't, I will do that. Then, go ahead and push that boot back on to the caliper bracket. I'm going to do that for both of those just to make sure everything is good. Then I'm going to go ahead and put that caliper bracket back with the 15 millimeter bolts. I'm going to fast forward as I reinstall those two 15 millimeter bolts. I'm going to torque the two 15 millimeter bolts to approximately 65 foot-pounds.
Take your pads and lube up with a little brake grease the ends that will get in contact with those calipers slide brackets, and then go ahead and slide them into place. Now, go ahead and take your caliper and slide it over the brake pads and onto the caliper bracket, lining it up with the two slides top and bottom. Reinstall the bolts that hold the caliper and the caliper bracket. I'm going to go ahead and fast forward through that. Torque the two caliper bolts to roughly 35 foot-pounds.
Reinstall the wheel. Put the lug nuts on by hand first, just to make sure you don't cross thread them. Then tighten them preliminarily. I'm going to torque the five lug nuts to roughly 100 foot-pounds and I'm going to do it in a star pattern. Torque that axle nut, the 35 millimeter axle nut, to 159 foot-pounds. Now reinstall your hubcap. I'm going to do that with that 19 millimeter socket. I'm just going to screw them in by hand. Also, you want to make sure that you line up the valve stem with the notch in the hub cap for the valve stem. I'll go ahead and fast forward through that.
Last but not least, whenever you have your brakes apart, make sure you pump the pedal. Make sure it's nice and firm before road testing.
