As I am a bit of a knob with them and know SFA about them, Well, little anyhow.
Today my foot slipped of the clutch as my right foot hit the loud pedal. With all that engine noise and stuff going on, I had time to look in the mirror and only saw one black line through the smoke. Must be a crook engine??.
Question is, It has a 3.5 Track lock diff in it. Could the clutch's be worn out??. Was the only thing on the car not rebuilt(the center anyhow)
Should I put one of these in

or just get a new clutch pack for it??
Opinions??
Merry Xmas

Traction lock does not use clutches. If it really is traction lock, something ain't healthy with it.
Limited slip uses clutches.

You will be able to put it up on your hoist shortly and have a look:-) are you sure it's a locker & not an LSD?

Pretty sure its a track lock as called for in the Marti report. As far as I know it is original to the car, as the diff tag checks out, 31 spline axels, N case.
I thought they had a clutch pack in the track locks?? like 4-5 clutch plates?? But I'm happy to be told different??

Looking forward to getting it. Poured the slab for it last thursday!!!

Traction-lok is just what Ford calls their limited slip differential. It has clutch packs hence they get old and do not function so well. Really is a bad design if your looking for a locking style differential. You can search the forum - we have had a few good discussions on types of centres - one where Hybrid and I put up exploded views of the various centres.


I will someday think of something clever to say.

Gotch ya. So would the part I have listed above be a good replacment? rather than rebuilding whats there? Mostly a street driven car. with ocasional loud pedal duties??

The description sounds as if it would be a better option. Having said that I did not find a lot of information. In any case, I believe it is a design detailed here.

I just do not know what it is your actually buying. Hence;

For a nine inch diff you have a lot of options. Based on your description I would consider a Eaton TrueTrac

www.summitracing.com/p.../make/ford

The ebay product might be fine - just need more information as I would not use it unless I was sure it was a quality product.

Doing a bit of research today, and it appears it may be a poo comp part. Think I will leave it there and go the Eaton if I decide to put one in
