boost69 Donating Members 737 Member For: 19y 6m 11d Posted 21/07/15 09:59 PM Share Posted 21/07/15 09:59 PM (edited) Guys,Had a bit of drag today off the traffic lights with some "hot shot" that pulled up on my left with like 20 meters of road for him to either make it or break it...Obviously I wasn't going to give up my pole position so I gave it a bit of a squeeze, but that dreaded axle tramp cut in again...Even though I have taken the car to Ford numerous times for this issue they still can't solve it...Just curious as to whether other FG XR6T sedan owners get the same axle tramp as myself...They also still can't figure out why the left rear end is still knocking, and I can confirm that the left rear end is where I feel it tramping...(It's like something is loose on the left rear)...the Ford guys cannot figure this out, they even changed a shock but this had absolutely no effect on the symptoms...

But if you take off hard in the wet it will spin and bounce sometimes (which is axle tramp yeah?).I too have a knock in front and rear...no one can figure it out but they say it has something to do with my swaybars (whiteline). Until I get some money for someone else to look at it...ive just been trying to ignore as much as I can lolHope you find an answer...try independent suspension place WITH A GOOD REP. Ford are ok for general things, but they just take it to specialists when they have NFI lol Link to comment Share on other sites More sharing options...

Solid bushes eliminated the axle tramp in both cases... Link to comment Share on other sites More sharing options...

Makes a big difference to rear end handling in all situations. Very worthwhile upgrade. Link to comment Share on other sites More sharing options...
boost69 Donating Members 737 Member For: 19y 6m 11d Posted 04/08/15 02:41 AM Author Share Posted 04/08/15 02:41 AM Guys,Got another mechanic to go over my car, in relation to the rear end knocking, and he couldn't see anything obvious either.This mechanic does do allot of mechanical work for taxis, so they have seen allot of suspension issues, and the only thing he could see that could possibly be causing that knock over bumps is the trailing arm bush.Apparently when the rubber cracks or wears, it can cause a knocking noise...What do you guys think?...

Try and turn off traction control and see if it still does the same noise or not? 1 Link to comment Share on other sites More sharing options...
BenDoCo I'm getten too old for this s**t Bronze Donating Members 4,509 Member For: 11y 7m 23d Gender: Male Location: A big bridge over a river in South Australia Posted 08/12/15 01:07 AM Share Posted 08/12/15 01:07 AM I haven't read anything but the last 2 posts so sorry if I'm miles off here. I have a single knock in the first few inches of movement (either forward or reverse) on mine. She will also knock 'sometimes' when I get off it and the zf does its little jumpy thing coz - I'm guessing - the valve body doesn't release the pressure quick enough. My problem is the outer cv on my right half shaft that was changed out to a repco unit about 5 or 6 months ago. When it's on the hoist, I can't reproduce it coz Don not strong enough to hold shaft and roll wheelI'll wait till it snaps and hit up warranty but the downside of that is my tuner won't put it back on the dyno till I fix it Link to comment Share on other sites More sharing options...
