I need some help.

I have a thunderbird 2L73 and whant to switch to a 3 27.

I want to transfert the traction lock from my 2.73 to the 3.27.

From what i rear i can remove the trac lok on one and put on the other.

1. Take it to a diff shop.
2. Say, "do it".
3. write a check
4. done.

My recent experience with experienced diff builders is terrible gear wine with new gears installed. They say it is because of the new gears themselves. Car sounded like it had a turbo back there... I put used gears in myself with much much better results. (not the miata but a 9 inch in a different car).

I will DIY that job... have no good shop around for that kind of job...

Maby i will take some picture to help the guy's here.

If you are just swapping from an open carrier to a Trac-Loc carrier, you should be fine. I am not really clear on what it is EXACTLY that you are trying to do. If you are changing gear ratios from one case to the other, you will need some special tools.

I have built many 8.8"s (1000+) during my Ford dealership days. If you don't set them up correctly, they will scream.

Just want to put the limited slip in the carrier from my 2.73 diff to the 3.27 one.

I have 2 complete diff and i don't want to play with the pinion.

Should not be a problem. Be sure to check your ring gear backlash before you remove the open carrier & make sure your locking carrier is set to the same backlash when you install it.

I agree with tbone --- just double check the backlash before and after and keep good track of any shims. I picked up a F0RD service tool set off of Fleabay for cheap that has the right pinion depth tools and case spreader ect. that makes the job easier now, but I did 50 or so swaps before the tools learning from Trial and Error and advice from a drag race friend that owns a trans / rear shop. They do howl when set up wrong, get very clunky sounding with too much backlash. Now with the internet available, a person can go in with some knowledge on contact pattern and what way to shim to adjust.

Sebz --- with your DIY talent and willingness to jump in and learn will do just fine.

A properly set-up differential will NOT whine. If yours does either take it back to the clowns who built it and get it fixed or fix it yourself. If you drive it that way very long it will be going back anyway and the repairs might not be cheap. I did not take pics of my 8.8 when I switched from 3.23's to 4.10's but the wipe pattern should look like the attached photo. Before some moron points out that this is not a ford; it is a GM 12 bolt posi but that does not change what a good wipe pattern should look like.

Thanks for the pic. don'T have time to swap gear yet. The Shop is full of car.

So is mine.
