Tools
Note: always loosed FILL first in case you cannot get it out. You don’t want to drain something and only then find out you can’t fill it.
Thread Sealer
- The factory threads have it, so good to use some
- Do not overdo it and don’t put the sealer on the very front of the various screws
Transfer Case
- Remove skid plate – 14mm socket
- 10mm allen for fill/drain
6 Speed Transmission
- Wrap exhaust with aluminum foil for easy cleanup
- 17mm allen (no need to cut – simply hammer out allen from socket)
- If you have a much longer one do need to cut, you need around 1.5″ length
- Harbor Freight sells a 17mm allen that you can punch out and the length is perfect
- Use 17mm wrench on 17mm allen
- 14mm allen for top fill
Differentials (Rubicon stock)
- .5″ ratchet + short extension for both axles and both drain/fill (no socket or allen needed)
