Prestin_xj Posted October 8, 2021 Share Posted October 8, 2021 Speedo help. The truck will have 37’s soon. Axles have 4.56 gears. What Speedo gear do I need to order for the tcase to keep the speed right? Buying the correct gear will keep the odometer accurate also, correct? Also don’t know if I need the short or long gear. Just did the 2wd ba10 to 4wd ax15 from a 96’ xj. The Speedo parts that go into the trans/tcase are different between the 2wd and 4wd transmissions. I won’t be able to use the cable driven Speedo off of my 2wd trans (it’s much bigger) so I’m going to take the Speedo mechanism off of my 87’ 4wd mj tcase.

Prestin_xj Posted October 10, 2021 Author Share Posted October 10, 2021 @Pete M yes! Looks like a 36 tooth should be close enough. Just don’t know if I need a short or long one Link to comment Share on other sites More sharing options...
Pete M Posted October 10, 2021 Share Posted October 10, 2021 I was able to swap the shafts from long to short. Link to comment Share on other sites More sharing options...
