How to Install a Gooseneck Trailer Hitch on a 2008 Chevrolet Silverado


Today, on our 2008 Chevy Silverado, well be installing the Draw-Tite Hide-A-Goose Underbed Gooseneck Trailer Hitch, part number 9465-34. Note, to begin our install, weve already gone ahead and lower to remove the spare tire. Next, were going to remove both sets of rear wheel. Once our rear wheels are out of the way, remove the back half of the exhaust by unbolting it here at the exhaust clench removing the three nuts and then the two rubber isolators. Once we do this, well go ahead and take the exhaust and set it aside for installation later. Next, well go ahead and get in the bed of the vehicle.

Well need to measure, mark and drill out for the gooseneck ball throat to come up to the bed. Using the measurements provided with the instructions, well go ahead and measure it out and mark it now. Then using a pilot bit, well go ahead and drill out at the center point. With that done, well go ahead and switch to our holes whole bit and cut out the large whole as per the instructions. Now, with that done, well then move back underneath the vehicle.

Next, well need to remove the exhaust heat shield between the bed channels. Well go ahead and use our paint stick, mark out the area and then use a cut off wheel to remove this section. Once we have the heat shield cut out, well go ahead and set it aside as it will not be reinstalled. Next, well need to remove approximately 1-1/2 to 2 inches of the heat shield that goes around the top of the fuel tank, here on the passenger side, as it will interfere with the cross rails of the new hitch. Well go and use a pair of tins nips just to cut this section off.

Now with that done, were going to go ahead and loosen the bed bolts here on the passenger side. Well actually back it out of our way and thread it back in a few threads enough to still hold the bed in position. Now, well move over the driver side, well go ahead and remove all four fasteners. Now with the bed loose, we can go ahead and take a block of wood and insert it between the hatch channel in the frame to help support the bed and keep it up out of the way. Now with the bed prop up, this will allow us to get the cross rails and gooseneck head into position above the frame rails.

Next, well go ahead and assemble the rails in head, taking the 5/8 carriage bolts, concrete tooth washers and nut, well secure the rails of the head. Note, the front rail will go in to the gooseneck head to the horizontal attachment points. Once we have the carriage bolts in place, well then go ahead and secure it with the concrete tooth washer, teeth of the washer facing the hitch and then the nut. Well install each fastener and finger tight to put them all in place. The rear rail, which is also be a shorter rail, attachments point will be vertical. Now with everything fingered tight, well go ahead and put the gooseneck into position above the frame rails, fitting it in on the driver side and up over the frame rails on the passenger side. Note, on the driver side, well need to first remove two fasteners and secure the electrical connector on the inside of the frame. Well loosen these fasteners and then move it up to the slided holes and out of the way. Next, well take the side bracket, put it over the gooseneck rails and into place of the frame. With the side plate then in position, we can secure it with the half inch U-bolt, half inch concrete tooth washer, teeth of the washer facing the side bracket and then the half inch nut. Next, were going to install the hardware and secure it to side plate to the rails, this will be a 5/8 flat washer then a split lock washer and a 5/8 nut. Now, once our all hardware is in place fingered tight, well go ahead and repeat the same process on the other side. Note, on the driver side, well be adding an additional L-bracket between the bolt and block as it will be the new attachment point for the wiring connector we previously removed. We have an additional attachment point here at the rear of the side bracket, this will be a 5/8 bolt, 5/8 block going to the frame to the side bracket and being secured with a 5/8 split lock washer and nut. Now, with all our hardware in place, well go ahead and tighten it down. Next, well torque specifications as indicated in the instructions, starting with the side bracket to frame attachment points. Then well do the bracket to frame rails and then the gooseneck head to rails. Next, well go ahead and re-secure the pickup bed by reinstalling the driver side hardware and tightening down the passenger side hardware. Now, with everything tight and torque specifications, well go ahead and secure the wiring connector to the L-bracket that we installed earlier on the inside of the driver side frame rail. Next, well go ahead and drill out for the chain hole down. To drill out these attachment points, well use the gooseneck as a template and drill out on the bottom corrugation of the bed. To drill them out, well go ahead and take our final size bit as per instruction and use it as a template. Once we have a mark made, well go ahead and use a smaller pilot bit to open it up. Now, with all our poles drilled out with a pilot bit, well go ahead and move to the top and drill down through the bed and through the hitch that we used as a template. Now with all our holes drilled out, well go ahead and put the U-bolts in place. Noting, that the driver side U-bolt will have a short leg on the front attachment point. Next, well get underneath the vehicle and secure it with the hardware. First well install the spring, the larger portion of the spring going on first, then well secure it with a half inch flat washer and lock nut. Now with all our hardware in place, well go ahead and tighten it down to secure the chain hole down. Next we will need to assemble the handle to our gooseneck hitch. The handle will come of the rubber grip that will go and slide on and into place and then well set the handle into position in the gooseneck head, well line up the pregerer holes and install the pin to secure the handle. Now, with our handle secured, well need to reinstall the vehicle exhaust. With our exhaust reinstalled, we can now go over operation of our new gooseneck hitch. The handle will be pulled out to unlock and push forward to keep it and then unlock position. We can then insert or remove the ball as necessary. This is what our ball look like once its in the towed position. To put it in the store position, well unlock the handle, pull the ball out and turn it over and drop it into place. Once in place, well go and relock the handle, locking the ball in the stored position. Now with that, these complete the install of the Draw-Tite Hide-A-Goose Underbed Gooseneck Hitch, part number 9465-34, on our 2008 Chevy Silverado.
