Gravelguy413 Posted August 7, 2021 Share Posted August 7, 2021 Can carriers from a 38k suspension be swapped into 44k axle housings ? Is there any difference between the two carriers?

D-Day Posted August 7, 2021 Share Posted August 7, 2021 Check the tag on the carrier where you find the ratio you should see a CRD 92 and CRD 93 there are other series of carriers those CRD numbers have to match also the axle spline there is a difference between early and late 17 spline deep v cut and shallow cut input shafts and yoke as well as torque arms may differ there are a few things to match up but is generally doable Quote Link to comment https://www.bigmacktrucks.com/topic/67650-carrier-q/#findComment-478057 Share on other sites More sharing options...

Gravelguy413 Posted August 8, 2021 Author Share Posted August 8, 2021 One truck is a 91 RD690s and the other a 96 RD690s but I will check those things Quote Link to comment https://www.bigmacktrucks.com/topic/67650-carrier-q/#findComment-478082 Share on other sites More sharing options...

Is there any difference between the two carriers? The carriers can be swapped from 38k to 44k axle housings. Mack top mounted carriers are swappable all the way from 34k - 58k axle housings. The only unique version is 65k axle housing with CRD95/96 carriers. These won't fit on any other axle housing or vice-versa. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/67650-carrier-q/#findComment-478489 Share on other sites More sharing options...
