Tech Tip: Dodge Promaster front suspension clunking

April 12, 2022
The technician was advised to do a thorough inspection of all front-end components and bushings for wear, excessive play or looseness, or collision damage.

Vehicle: 2018 Dodge ProMaster 2500, V6-3.6L, automatic transmission/transaxle

Mileage: 64,572

Problem: The owner brought his Dodge ProMaster to the shop because he was hearing a clunking noise from the left front suspension area while driving. Another shop already replaced the left front strut, sway-bar links, and front brakes, but the problem persisted.

Case Details: The technician road-tested the truck to verify the complaint. He found the noise occurred primarily when hitting bumps in the road. An ALLDATA Tech-Assist consultant recommended a thorough inspection of all front-end components and bushings for wear, excessive play or looseness, or collision damage. He also advised inspecting the recent repairs done by the other shop to verify everything was installed correctly and to check that all the fasteners were tightened to specification, including the crossmember bolts. As a final recommendation, the consultant said that if no issues were found, he would recommend using Chassis Ears and road-testing the truck to help isolate the source of the noise.

Confirmed Repair: The technician performed all the inspections as advised and found the upper strut mount was not replaced with the strut and was causing the clunking noise. He replaced the left upper strut mount and road-tested the truck to verify the repair.
