hi i've been piecing together my beater 94 tracker. I now have a problem when i put it in 4wd when i try to move my tires start to skid and skip. What would cause this and what do i need to do to fix this?
Does only one axle do this?
I bet that you have inadvertantly installed mismatched differentials or have different-sized tires from front to back. If the differential gear ratios are not identical or the tires are not all the same size from front to back, skidding slipping and popping will occur followed by damage to the differentials and/or the transfer case.
If all the tires are the same size and you have swapped in one or both axles with "new" differentials, double check the gear ratio on both to see if they match.
- Lift one wheel off the ground
- Put the transfer case in neutral
- mark the input flange and adjacent case on the differential with white-out.
- Do the same on the inside of the tire and on the brake dust cover.
- Turn the lifted wheel one turn while counting the number of rotations (fraction included!) on the differential.
- Write down the resulting number of turns
- Repeat the above process on the other axle
Both flange rotation numbers should match. If they don't, you need to swap out the "bad" differential with one that has the gear ratio that you want to keep.
Hope that this helps!
