In this regular column, Autodata’s Technical Team share their fixes to common problems raised through Autodata’s technical helpline, available to all UK customers. This month it’s a fault on a Jeep Wrangler.
We are having trouble finding the source of a rattling noise coming from the front of a 2015 Jeep Wrangler when driving over rough roads. We heard the noise during the road test, so tightened all the nuts and bolts on the suspension. However, we cannot find the source of the rattling noise. Is this something that has been reported before?
Yes, the fault you describe affects all Jeep Wrangler models built in 2015. The cause of the noise is due to incorrect specification of the front brake caliper sliding pins. Inspect the front brake caliper sliding pin heads for grooves (Fig 1.1). If grooves are not present, fit modified front brake caliper sliding pins. Carry out road test to ensure the noise has been eliminated.
