personally i don't mind paying someone to do something that i can't do... but on the other hand, i know i can do any of it with the right training and supervision. I'd like to lear for myself, even if i never touch another diff. again, just knowing that i could if i wanted to would make it all worth it to me...as for buying the tools, if the parts and tools cost less than 1500- i figure i saved money, and if and when i need to do it again...i have all the tools, and the know how to do so... So, if there are any obscure reference sites that could be shared with me, i'd appreciate it. As for that special 8.25 tool, i'd love a picture if at all possible. All i can do is hope for the best, and if it breaks when i go to use it then that's just how the cards fall...i'll have to suck it up, buy new parts, and try again. I am never ithout a vehicle at home, there's 3 of us, and 4 vehicles. the only time they take the other jeep is when the take the motorhome too, that's the tow vehicle. But them i'm left at home ith the choice of 330 convertible, or 740 sport... hmmm, choices choices... anyways, sorry for the tangent, I need adderall! I really want to learn how to do this, knowing that this WILL NOT be the only time it is useful makes it that much easier to decide. Point me in the right direction folks, i think i'll try and find a cheap 8.25 to re-gear for practice.
