Sending my FRS gearbox off to Bara Motorsport for a rebuild as 3rd gear seems to be needing attention.

I bought this box second hand off eBay years ago and just got it in and working so I could test it.

Is there any way by looking at the diff through the driveshaft holes that I can be sure the quaife diff is still intact?

In short no. Those spiral grooves tell you it’s a quaife diff though

Thanks mate all I wanted to know.
Had a horrible feeling the diff had been removed seeing as I've been sold a box as good working order which isn't.

Also if I was you I'd send it to Steve at Northampton gearbox centre. He owns a focus rs and has rebuilt dozens of these boxes. Waaaaaay cheaper than anywhere I found.

would you be able to let us know the diagnosis and cost? am thinking to do same whilst the box is out.....

Cheers for that. Mine needs to come out of my escort.

Ps my diff looks like the one in the first pics.

Steve has built loads of these boxes for the owners club members.
Mine was blasted powder coated new diff bearings many new other bits and bearings. Less than £400.
He does look after the OC members though. Give them a call and ask for Steve.
