2008 Chevrolet Colorado Muffler Parts Questions & Experts Answers

• Q: How to replace the muffler on LLV - 2.9L/LLR - 3.7L on 2008 Chevrolet Colorado?

  A: Before changing the Muffler on llv - 2.9l/llr - 3.7l vehicles raise the vehicle carefully while maintaining support and avoiding stretch of the rear brake hose. The first step involves removing nuts and bolts attaching the lower shock absorbers. Afterwards remove the right rear leaf spring bolt and nut. Set a wood block between the frame and rear axle while being cautious to avoid joint flex or damage. Now remove the Muffler nuts from the Catalytic Converter but avoid using oil as a lubricant. Add soapy water to the Exhaust Hanger rod attachments before prying the hangers off their position. Start by pulling the Muffler back from the Catalytic Converter and turning it counterclockwise by 90 degrees before removing it carefully. To install the Muffler properly place it over the rear axle with a 90-degree counter-clockwise turn while positioning the flange near the Catalytic Converter before rotating it 90 degrees clock-wise toward the installed position and push it forward to match the stud locations with the rear of the Catalytic Converter. Do not select oil-based lubrication products during this installation process. A soapy solution should first be applied to the inner diameter of both the exhaust pipe hanger and exhaust pipe hanger rod before their installation through rod insertion. Install the Muffler nuts on the Catalytic Converter until the metal flange area forms contacts manually then torque them to 45 n.m (33 lb ft). Fitting the right rear leaf spring bolt together with its nut requires 85 n.m (63 lb ft) torque then move to tightening the lower shock absorber bolts and nuts to 95 n.m (70 lb ft). Prior to lowering the vehicle inspect the exhaust system to check for leaks and underbody contact.
