annmax Posted July 15 Share Posted July 15 Mack Granite 2021, i hear a loud clunk coming from the front suspension when i fully press the brake pedal at a stop or a red light. Nobody can find where it coming from. Any ideas ? Quote Link to comment Share on other sites More sharing options...
fjh Posted July 16 Share Posted July 16 Have someone check the front pins for seizure quite common on the Volvo trash suspension! 1 Quote Link to comment Share on other sites More sharing options...
The Heinz Posted July 16 Share Posted July 16 I second FJH, the pins on the leaf spring fronts don't hold up very well at all, regardless of whether they were greased or not. If you've got drum brakes, you might have some trouble there; we've got one of our church buses doing similar with a loud clunk in the rear when stiff braking. The slacks don't adjust properly, and while I haven't had a chance to check, I'm willing to bet the s-cam bushings are wallowed out too. 1 Quote Link to comment Share on other sites More sharing options...
Mackpro Posted July 21 Share Posted July 21 In the last few years we have seen that the factory doesn’t grease or tighten any thing very good. As in no grease on the king pins and front steer axle U-bolts loose. Sometimes the dealership catches it , sometimes not. I vote spring eye bushings or loose U bolts 2 Quote Link to comment Share on other sites More sharing options...
Popular Post fjh Posted July 21 Popular Post Share Posted July 21 This is why we do pdi inspections and incudes greasing and checking for missing or loose bolts ! Once ran across an mr with a bolt missing on the rh steering arm for the tie rod ! Also a loose steering box missing spacers! Simple oversight’s the could be disastrous for every one involved! Like wheels falling of jets not a great scenario! 2 1 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted July 21 Share Posted July 21 I have seen missing u-bolts on steer axles and loose clamps on exhaust, , Heck the P.D.I. check list is a few pages long, 2 Quote Link to comment Share on other sites More sharing options...
