Trac loc recommendation
#1
Hey guys,

by changing the clutch I will do my rear end a favour and would be install a trac loc. Which spline should I go, 28"?

I have a 3.50 rear gear, 4 speed manual and 275/60 R15 tires on the back.

Any recommendations? Which should I choose and which points should I pay attention to?

Thanks,

Tim

The Trac loc you get will depend on the number of splines on your axle shafts. You probably do have 28 spline axles, but if it were me I would pull an axle and count the splines before I took a chance on getting the wrong one and have to pay for shipping 3 times.

if they are OEM axles then most likely 28 splines. if you have drum brakes then it's super easy and fast. if you pull out the axle and all of a sudden you see a taper down to a small diameter, then its 28s. only the higher models like boss's had 31 splines from the factory. but who knows what you have under there.

Depends on your axle.
Pull a wheel and look at the axle.

Correction, just remove a hub cap.

Ok, that helps much!

If so and I have the 28 spline in my back which one would you recommend out there? Which one would be a plug and play trac loc?

Thanx,

Tim

Auron,

thank you! That's a big amount of money - what's the benefit buying this whole assembly over getting only the posi unit like this

http://www.ebay.com/itm/9-Inch-Ford-28-S...0996109904

Did you install it by yourself? Your experiences?

Thanx,

Tim

Sure, you can have someone rebuild your 9" rear end and convert it from open differential to a trac-lock differential. You just need the carrier and a rebuild kit that contains all the o-rings, seals and bearings. Jegs and Summit both have kits that include everytnig you need, including the gear oil and ltd slip differential additive.

Plug and play, you don't have to worry about preloads, gear lash, or the crush sleeve, but with your axle shafts out replace the seals in the axle tubes and check your bearings ect. ect. I have not purchased myself yet but I had these recommended to me by a friend and I plan on getting one in the near future.
