Baz Meredith addresses a severe engine rattle on a 2016 Volvo XC90 2.0-litre diesel and demonstrates why relying on traditional track rod replacement tricks is a risk for workshops.
After removing the auxiliary drive belt to isolate the noise, Baz traced the heavy rattle directly to a failed crankshaft pulley damper. Replacing the worn unit immediately resolved the issue before proceeding with the timing belt service.
During the timing gear replacement, Baz locked the fuel pump using a 5mm pin before installing a new Schaeffler kit and water pump, using Elring Curil T2 sealant to hold the paper gasket in place while vacuum-filling the cooling system.
Finally, Baz put the common practice of counting turns during track rod end replacement to the test. Checking the XC90 on a four-post geometry rig showed front toe was severely out in the red, proving that physical wheel alignment is essential after steering repairs.
