I have been looking and have seen several post describing a similar issue but have not seen any resolution. My 2012 Sierra just started jerking either left or right randomly. The more I drove it I realized the steering wheel was also cocked a few degrees of center...then after a "Jerking episode" the steering wheel would be cocked off center but to the other direction. 7 weeks ago I put in 2" spacers to level the truck. In the process I had to replace both upper control arms. I took the truck in for an alignment and they replaced the ball joints on the lower control arms. Now $800 later and maybe 300 miles my truck is jerking left during hard braking or right during acceleration. When I say jerk I mean puts me in the other lane or almost off the shoulder. The only other time it jerked was when I hit the first set of rumble strips coming to a stop sign (before I began to brake)....almost like something jostled and caused the same jerk that put me well over the center line. At this point it is not being driven until I get it looked at or fixed. Checking to see if anyone has ideas or a known cause so I can get to the root of the problem right away rather than have a shop guess and come away only with hundreds of dollars spent with no solution. This is my weekend vehicle for the most part so it hasn't been used a lot since the alignment and surely hasn't been abused.

John Goreham Contributing Writer, GM-Trucks.com 9-7-2016 Owners Jeremy & Misty Nelson and Terry Jostock, and Price Motorsports LLC, have created one of the most powerful Chevy trucks in the world. We thought the GM-trucks.com readership might like to know a little more about what goes into creating a truck with 2,700 hp. Dusty Price of Price Motorsports was kind enough to pull back the curtain and give us some details. - Describe what the truck is for those that might not know what a Pulling Truck is. A pulling truck is basically the Top Alcohol Funny Car class of pulling. The truck weighs a maximum of 6200 lbs with the driver and full of fuel. The truck is 15 feet from the center of the rear tire to the farthest point forward, and limited to a 575 ci engine with a 14-71 hi-helix supercharger. - Please tell us about how the idea for the truck started. What was the inspiration and the goals? This truck was started as an experimental piece. It has all of the latest and greatest engine, driveline, and chassis components. While we didn't believe this truck would be a winner all of the time, it has proved to be very successful right out of the box. It is owned by Jeremy & Misty Nelson and Terry Jostock. - Tell us what underpins the truck. What is the basis of it and how did you build it up? The chassis with what we call a wedge design frame. It is pressed metal in the shape of C-Channel but wider at the rear and more narrow at the front of the truck. There are also tube designs out there but this Jostock built frame has proved to be a success. The driveline starts with a 3-4 disk Crower clutch inside a Probell bell housing, after that there is an SCS Gearbox reverser and 3 speed transmission. The driveshaft then travels to the rearend into an SQHD center section (the side of a semi truck center section) and out to the SCS Gearbox planetaries that power the 18.4x16.1 tires. - Give some understanding of its specs and what it is capable of. How did you measure the specs (hp, torque etc) The engine being upwards of 2700 hp and 2000 ft/lb of torque is pretty cool. These trucks are known for their wild wheelstands down the track. Plus fans like to root for their favorite brand of truck. It generates some friendly rivalry for them, which makes it fun for us. - Has it won any awards? This truck has won several pulls already this season, and won several fan votes. So the guys are pleased. - If you could go back to the very beginning and do one thing differently, what would that be? I believe if we were to start over, we would probably put more money into the engine. While we also push our equipment to the max, the supercharger is a vital piece to success. A blower can make or break your program. - Share your time investment with us (man-hours, years of work, however you like) and only if you want to, what dollar value you would estimate the truck to have. The truck was built in just over 3 months. The chassis was bought as a roller with the entire driveline from SCS Gearbox already assembled, the body was already made specifically for the truck from GTS Fiberglass, so it was easier to mount. And these hemi based engines are very easy to install, even with the entire clutch assembly and Probell bell housing bolted on. So overall it is an easy puzzle to piece together. The dollar value of this particular truck is in the $150,000 range. The engine alone is pushing around $90,000. Thanks very much Dusty. GM-trucks,com would like to thank Tim Esterdahl and Craig Daitch for bringing this story to our attention.

Hey guys I recently got called to give an estimate for a tricky job. A customer has a tree hanging over the river in their property they want removed. The tree is not gigantic and would be extremely easy to manage if it were on more solid ground. However, in this case it is not. I have a 2007 Silverado 1500 4x4. I thought that it would be possible to tie a rope or heavy tow chain to the tree, cut the tree, let it fall into the river, and then use the truck to pull it up onto the bank so I can cut it up from there. Therefore, my question is: How should I got about doing this? Should I connect the chain/rope to one of my towing hooks or my trailer hitch? If I had to estimate I would say this tree probably weighs around 600 pounds, no more than 800 pounds. The plan is to have it loosely tied to the truck so there is no pulling while the tree is falling. I thought I could get some advice from here. If I thought the job was too much I would have turned it down already. I still might turn it down. However, I believe that it is a manageable job. So what should I use the trailer hitch or towing hooks? If I use the trailer hitch I should probably go around the solid bar the actual hitch is connected to right? Also I need a little more than 25'. Can I connect two tow chains together to get the length I need? I would be using two of these: http://www.homedepot.com/p/Everbilt-5-16-in-x-20-ft-Grade-70-Tow-Chain-with-Grab-Hooks-803082/203958797 Alternatively, I have a very long rope that is pretty strong too. Probably, not as strong as the chain, but definitely an alternative. I should have taken a picture while I was in the customers property, but I did not.

I Have for sale a Tekonsha Prodigy P2 trailer brake controller. Was installed in my 2009 Sierra, removed after an accident thanks to some idiot pulling a 36ft travel trailer in a blizzard (yes I know I shouldnt have been driving either ). Anyways its in perfect working order, comes with the manual, mini cd, two mounting options, and harness. Anyone who knows trailer brake controllers knows this is one of the best on the market. Retails for $105+tax regularly. $75 FIRM, SHIPPED!
