Questions! Need Help
So I will post up some pics and try to be as clear as mud with my questions,
REAR DISC CONVERSION
I am going with the usual GM rear disc setup and think I have all the facts after doing some searching but a few q's come to mind:
?? - I am going with an H55 tranny / TC combo in the FJ55 because of the 5 speed. Does the TC on this combo have the same rear emergency brake as the fj40? I believe I read that it does not and uses the common linkage to the caliper for an emergency brake. When going with GM rear discs I could not find a solution to implement an e brake?
I have heard others mention a "line lock". I believe I understand what a line lock is that it basically uses the standard braking system to lock the brakes on, correct? where does one get one of these and are they all electric or are there hydraulic ones as well? Are they safe to use as an ebrake? I think I would feel better using a hydraulic one rather than an electric one, just seems more reliable to me.
I also saw that JTO or another supplier ? has rear calipers with the e brake mechanism on them BUT they are very expensive and I just don't have the budget now, so I am looking for a solution that is reasonably priced. I saw a post that POSER put rear calipers with the ebrake mechanism on but could not figure out the linkage to get it to work right?
What are my options and what do you reccomend for a solution?
?? - Am wondering if anyone sells just the milled rotors for the GM rear disc conversion? I already have the brackets from the previous owner and could get them milled at a machine shop but for a few extra $ I would not mind just ordering a set that are pre-milled.
REAR AXLE QUESTIONS
?? - I have inspected the differential and attached a pic of my pinion gear where you can see if you look closely the chip in one of the gears? Is this a fatal problem or can I just run this as is? If it is not a big deal I will just run it but wanted to get some opinions as to issues I may run into because of this small chip in the gear tooth. The rest of the gears look fine. I have attached a pic of the splines on the axles as well as the ring gear, what does everyone think of the shape of these? What should you look for when inspecting gears on a rear differential?
?? - I also inspected the pinion bearing and don't see anything obvious. I have no idea how long it has been in the diff as I bought the project as is. Is it reccomended that I replace this and the rear pinion seal or should I leave it alone? The rear pinion was not leaking at all from what I could tell. I suppose if I have to replace the pinion gear this is a mute question. Any opinions appreciated?
?? - When I pulled the rear axles and c clips the spider gears fell out, 4 of them. I see how they fit back in but was wondering if there is any specific way that they need to be placed back in? or can you just place them back in as best as possible and align them with the axles when you slip them in?
?? - What is the best way to install new rear axle bearings? I was thinking of freezing them and then installing them in the rear axle to help them shrink a bit. I have a seal/bearing driver kit. If I do put them in the freezer should they be packed with grease before hand? this way they can go in right away while still cool. I am sure my wife won't mind some axle grease on the frozen lunch meat,
Sorry for the long post, any help is appreciated!!
