the tuner had the car on the hoist fitting the new exhaust & other goodies & was checking everything out & found that the main diff bush was cracked. I figure this must be abit of an issue they have when you start putting some hp through everything. just wondering has anyone found a replacement bush instead of the ford one, I dont want to be replacing it 3 mths down the track. the cars only 9 mths old with 20000 klm on it & has been modded slowly along the way. is putting out around 500rwhp so its only gonna happen again I think with factory bush.

thanks john

Have a read here, after market units are a bit noisy.

Bush Thread

Pedders in Moorooka Queensland do a nolthane diff bush it's meant to last longer mine were replaced under warranty 2000kms ago

its a rock & a hard place I guess. if you put the harder bush in you get extra noise & potential stress but if you put the ford part in its only gonna crap its self again. they dont want to know about warranty because its modified but I dont know how long its had the prob for. it hasnt been down the track since it was stock & since its been modified I havent raced it. its spent more time at the tuners then in my own garage. im not so worried about the initial cost its the on going if it happens again. does anyoneone have a costing on it from a ford dealer including cost of the part? its a bf mkii with 6sp auto if that makes any difference

The majority of the noise NVH mine makes is when coasting (closed throttle) in gear, you can hear gear chatter from the diff that was insulated before. Yours being an auto may not make any of this noise as when it coasts it doesn't have the same engine braking so it might be fine. Beauty of this bush is if it fails again it can be changed alot easier than the factory as its not pressed in and doesn't have a metal shell around it, if you were to drill a hole in the spare wheel tub about 25mm you could replace it without dropping the rear end.

thanks for that, that's the info im looking for. prob being the ba version 75mm bush has been out for a while but from what ive been told the bf is a 90mm bush. has anyone replaced one on a bf yet (90mm).

Hi flare6t.

I don't think the aftermarket jobs have been made yet. I tried Fulcrums and Pedders 6 weeks ago and they didn't have any developed or made then. Clever Ford went to a weaker one in the BFs than what the BAs had.

Looks like regular OEM replacement until the aftermarket boys pull finger. I think mine is living on very borrowed time
