Fg Axle Tramp .. Or Diff Bush?

[senna_T]

Looks like you have an early comfort series (SPF3232AK) which is proving quite soft...

Give me a call and we can work something out for you

Thanks Pat, will give you a call. Cheers,

Thanks for the chat Pat, I placed the camera to look at the right hand side front bush to see whether you can identify whether it is the Superpro comfort series or other. Looks very soft and given I get very little NVH through the rear, I presume it is the early comfort series. I will give you a call to discuss the best alternative as it certainly can't stay the way it is.

I have harder rear bushes... No axle tramp what so ever... ever.

Though nvh noise would be a pita if I didn't have a noisy zorst.

It was the bushes that got rid of the tramp. I have the Koni adj. too there at full lock now but when they were loose as it made no dif.

I have noticed axle tramp on my car also...and my diff bushes were done in December last year.

To be honest, it never did it prior to Ford changing the bushes, so I'm not sure what the go is there.

It's really annoying, as the whole rear end shudders when you take off really fast, where before it used to just slide out, grip, and go.

Definitely the early comfort series there - you can tell by the length of the voids

The design of the diff mounting in our cars leaves a lot to be desired IMO.

To me, I would fit nothing but the unvoided SuprPro bushes to give it the best chance it can get.

It is good to see that all 3 bushes have been changed. If only the back bush is changed for poly, it will disproportionately load up the rear bolt and trash it (and/or the alloy rear case).

Has anything been done to the blade link bushes? They are the sloppiest (most heavily voided) bushes in the whole rear setup. How they can have any hope of controlling axle wind-up is beyond me.

They have the biggest input into controlling axle tramp. Once you see them out of the car and examine the rubber portion inners, it will be apparent how "loose" they are.

I have a MK2 FG XR6T, its a manual and its only got 7000k's now since I bought it brand new. I've had the axel trap since the day I got it, just haven't got around to doing anything about it as of yet, but its that annoying and noticeable that you cant even plant the go pedal without it tramping now.

Even with traction on, if you are on a road that has less than ideal grip on it, planting the pedal results in tramp. Don't know if replacing the bushes would actually help or not or its a warranty issue.

All appears to be fixed. The guys at City Suspension at Penrith really looked after me, fitting the new bushes at no cost (or labour). Excellent service.

They fitted the Superpro competition bushes (front and rear). I do now get a little more vibration through the car (I expected that) however, it is not unpleasant or annoying. Mainly noticed when in overrun in first or second gear.

The diff does still appear to bounce a little however, nothing like it was.

And not a hint of axle tramp either. I suspect it was the diff all along, not axle tramp.

nice one!

just how much power does it take to turn the tyres like that?
