Carbon buildup on the top of the pistons is common. As the buildup increases with over time, symptoms vary from light ticking, to hammering, to knocking noises. Performing a fuel injector cleaning procedure can often help the condition by removing some of the piston top deposits.
The door glass may be hard to roll up and/or come out of the run channel. Our technicians tell us the repair can include adjustment of the run channel, regulator to glass, regulator to door, and if necessary shimming of the window regulator.
A squeal or squeak type noise may be heard from the rear brakes on application. Our technicians tell us there is an updated rear brake pad shim kit which can help reduce this type of noise.
The manual transmission may become difficult to shift, this is commonly caused by binding between the synchronizer and the gear surface. Adding a special friction modifier to the manual transmission fluid will often correct this condition. If the problem persists revised synchronizer kits may be available.
The 80 amp fusible link for the charging system can fail and is often overlooked when diagnosing a charging system that is not working. Our technicians recommend to make sure this fusible link is OK before replacing any charging system components.
The transfer case may develop a leak at the driveshaft yoke which can result in a low fluid level leading to transfer case failure. It is recommended to monitor the transfer case for leaks and repair as necessary.
The power transfer unit (transfer case) and/or viscous coupling may fail due to unequal size or oversize tires. Use of incorrect or mismatched tires can cause the front and rear wheels to fight (driveline wrap-up) resulting in drive train failure. Our technicians recommend to use only matched, correctly sized tires and keep them properly inflated and rotated in order to maintain uniform tire wear.
