Ive resealed many a steering gear box. The SLs are the ones that take a little longer due to the need to remove the exhaust pipe. On a good day I can do the job in 2 hrs start to finish. I have a date coming over for some quality time if you know what I mean....

It will take me at least a half an hour to type a full detailed job instruction. Ill get back here later on tonite or in the morning and do it. Dont worry its not as bad as you think. But be careful when doing the reseal. If you disassemble the box too far you will have to deal with 17 if I remember correctly steel balls and if you lose one your screwed! The first time is always the hardest, but once done its not all that bad First time skill level 8 2nd time 4....
