Faulty New Diff Bush(S) = Diff Damage?

[Spoony]

cheers, good info to go back to them with. 3x removal of the coon rear end, they gotta be enjoying that! lol

You can see why people just stick with the OEM bushes allround. Ford have revised the rear one I've been told for FG. I think when my time comes I'll go with the comfort centre and OEM sides. That seems to be the safest best.

Update: The backend has now been out for the 3rd time. Fulcrum (despite the work originally being done elsewhere) have fitted 3x 'comfort' turbo style bushes, the car now no longer has epic diff whine, driveline clunking etc etc. Given the factory bushes lasted till 140,000kms with only minor cracks (the car doesn't cop that much of a hard time), I would expect the Superpro bushes to exceed this (else why bother making them?)

I recently removed the two front comfort series bushes from my car. Both had split. Superpro/fulcrum have been excellent in thier follow up service. I emailed the company with some photo's of the split bushes and within 4 hours I had a response from the companies GM. They have replaced the split bushes with another set of 1348ak's and have also sent me a set of trial bushes that are firmer than the comforts but not as harsh as the solid bushes. I will be returning the old bushes too SP so they can examine them and hopefully find the cause of failure.

This is why we use the Super Pro bushes - you won't get that sort of service from any other manufacturer

Their reasoning for the first failure was a faulty centre bush. Where the steel sleeve/insert was not bonded to the bush. So it flogged out allowing too much movement also then killing the other 2x bushes. I did hear mention about the newer sort bushes you have described, but didn't want the harshness already experienced (it's a daily that gets driven lots!). The Fulcrum guy recons that even the 'comfort' ones are more durable than factory, which is all I'm after. The difference vs only a comfort centre and solid outers is huge.

I'm quite happy with Superpro/Fulcrums follow up on these issues (only complaint would be that they supplied/recommended the solid ones on the 2nd refit to the original suspension mob). Less impressed with the service from the initial suspension mob that did the job initially though.

I would agree with that comment, Im not sure if mine are a faulty set or there is an issue with the comfort bushes on higher horsepower manual cars. Fulcrum have told me they are determined to find the cause. They are very keen to examine my old bushes and for me to test out there new trial bushes. My car makes aprox 350rwkw but has alot of traction due to the size of my rear tires so its a good test case for the new bushes

[Spoony]

How long were they in for? I know they pulled stock back off the shelves at the time I had the issue. So my guess is I wasn't the first, just maybe the confirmation? I'm only at 290rwkw 6sp auto, so certainly easier on things than yours. Not much more than stock F6 power really.

Only about 3000k's. They both let go at the same time. It wasnt a knock that got progressivly worse. There was no noise then after a hard 2/3 shift it starting to knock. The diff move that far it bent the front two mounting bolts (which appear to be made from high grade liquorice)

How are these bushes going now?

I've just gotten a quote to do all 3 in superpro comfort for ~$600 including the bushes, but don't want them to fail as I plan on modding the car for 350rwkw.
