Outer Limits 4x4 Board

hay all my gq patrol has a pretty full on knock under carridge when going over a rough road or when turning on a rough road i don't think its the exhaust banging is there anything alse under there that could be banging
also its fairly intermitent sometimes it needs to be a fairly rough surface to bring it on thank you all

gee thats a pretty broad question, it could be anything mate...

body mounts
worn bushes in links/radius arms
tie rod ends
wheel bearings
engine mounts



check them all

Gearbox mounts, panhard rod bushes, panhard mount to chassis, crossmember bolts loose

Get under and tighten all the bolts
