I only had the cradle and all out of the car 2 weeks ago to replace the bushes and diff, but it appears that there must have been a fault or hairline crack in the alloy where the bolt goes in..... and it broke a piece off the top, and now the bolt just swings in the breeze! Is this a common issue, or could it just be the result of the extra play when the bush was flogged out? Cheers Ken Link to comment Share on other sites More sharing options...

My car is producing 612hp at the treads, and has destroyed 2 bushes since I got it 2 months ago..... The first was a rubber OEM type with the shell, so I fitted a solid blue urethane one, but it quickly broke free of the alloy tube its bonded to and was forced out of the tube on the cradle and over the head of the bolt? (I have fitted a 45mm washer/retainer to hopefully resolve this issue with the latest bush) I replaced it with a nolathane unit with the relief holes in it, hoping that they will absorb some of the load.

ken666 Donating Members 140 Member For: 5y 3m 23d Posted 01/01/19 07:55 AM Author Share Posted 01/01/19 07:55 AM that's a much better design than the original. I will be building a new diff with lower gears to compensate for the turbo lag and the new cams I'm fitting in march, I will definitely fit a kit at the same time. As the car is my daily driver, I wouldn't receive the parts before I return to work on the weekend. But I do have a spare cradle and diff assy that I will prepare ready to swap out. Thanks for that tip Link to comment Share on other sites More sharing options...
