Detroit Truetrac - Speed Sensor

Hello All. I'm planning on installing a Detroit Truetrac (DTL-912A553) in the rear (8.25) of my 2004 Liberty. I noticed it has a sensor on the top of the axle housing which I'm assuming is a speed sensor. Will installing a Truetrac create any issues for this sensor? Thanks.

No, that on top of the diff for the 02-05s is a pickup for the ring on the rear diff ( for speed )
I have ran / run DTTs in both my 03 and 04 with no issues at all
The 04 I have ran ran for over 100,000 miles and the 03 about 80,000 so far

This is good to know. Thanks for the info Tom.

I also have a DTT in the rear axle on my 2005 with no issues from the sensor.

You'll either need to remove the tone ring from the original carrier and install it on the TT, or buy a new one and install it on the TT.

I used the ring gear to press it on, no idea if thats a good or bad idea... I tried putting the TT in the freezer and heating up the tone ring but that didnt seem to help anything.

I have a 06 KJ Sport I thought I had this figured out is the rear axle an 8.25 Chrysler or a dana 35 on Amazon it says the axle is a Dana 35 27 spline. Can anyone clarify why there is so much confusion?

Have you checked for your Build Sheet? This was a big help for me, just enter your VIN.

Thanks, I have never looked at a build sheet before its cool lots of info. It says 8.25 rear axle.
