Hello

1. Is this pic an 8.8 due to the Square-ish pot cover?
2. If when I open it up and find an open Diff, can I just find/order the Trac-Lok carrier.

89 5.0

At the Ford dealership the other day , they ran my VIN and said this car should have the 7.5 in it and it’s an LX 5.0 not GT model,
So I’m guessing someone went ahead and did the GT Ground KIT.

I’m learning quite a bit about this car I’ll say, some good, some not so great, but if the Diff can be converted I guess that’s on the win side..

Thanks Folks.

Just check the sticker on the drivers door jamb, if you can't read it or it's missing jack up one rear wheel, with trans in neutral, try to spin the tire, if it spins with no resistance it's an open dif.
there should be a tag on one of the cover bolts too. I see in the pic yours is missing, that cover has been removed in the past.

All 87-93 factory 5.0 cars had 8.8's if the 8th digit in the vin is E its a factory v8. The stock track lock can be rebuilt ,most will upgrade to a 31 spline unit with new axles. Explorers, are a good source for both gears and a 31 spline unit, just need axles.

This.


If the 8th digit is an E, then it's a factory V8. An LX 5.0 came with an 8.8 with a limted slip differential. That's an 8.8 in the OP's pic. There's a limited slip inside, although it might be worn out and need a rebuild

Actually, the 8.8 traction look started in the ‘86 V8 cars, GT and LX.
