New diff needed
So my diff exploded whilst on the track on Tuesdays (Cadwell UK).
What are my options? I have read quite allot on the board about aftermarket diffs but I don't want to spend thousands upgrading the rear end. (puddy mod vs ford diffs vs OEM) What is the best/cost efficient option? is it to just keep using standard OEM units as they are cheap? Note: Car is SC'ed 19 psi CT Engineering kit (novi 1200). Thanks |

Dropped him a PM.
What stage/ spec do boosted track users get? |
Ben Herne, the puddymod guy can speak to you in depth about why these diffs fail and how to prevent it from happening. I did see there is now an off the shelf billet crush sleeve replacement now available.

i believe if you're going to replace the crush sleeve, you're at the point of rebuilding the diff right? might as well get a rebuilt diff from puddymod anyway? |

can you elaborate on this billet crush sleeve? is this a common failure part due to the pinion nut backing loose over time?

If you're mechanically inclined, replacing the sleeve is a fairly easy task, it's also significantly cheaper than a fully built diff from puddymod. He can speak to you about the benefits of his diffs though, as there are quite a few. |
Thanks for the reply, it's shame I didn't know this earlier or I would of done this as a preventive measure. It's to late now as my diff is damaged.
If I can sort the shipping out then I will be purchasing a puddymod. |

The pinion nut should back loose. But compressive forces cause the crush sleeve to become crushed over time. Crush sleeves are used in OEM applications because it's a quick easy way to set preload without the need for lots of shims. But if it becomes over compressed, there is no longer any preload, and it cannot maintain proper pinion depth. When it cannot maintain proper pinion depth, that's when bad things happen. A billet sleeve replaces the crush sleeve. A billet sleeve will not become compressed.
