Excellent upgrades. Look forward to seeing completed unit, and hear results. I used a 1997 Trans Am rear end complete R&R for my upgrade on 1983 Camaro, super improvement! Thanks for great vids.
The guy who rebuilt my axle did it wrong so it lunched a pinion bearing immediately. fixed it, but now it's a little noisy because of that. the TRU Trac is pretty amazing. i can give the car 100% throttle in a turn and it doesn't spin tires, it just slingshots me around a bend.
@@3rdGenGuy Bummer on the failure. I must agree, the posi diff and disc brakes conversion brought my car to life, way more enjoyable. I also dropped from a 3:08 to a 3:43 gear. The result gave me better power band. Hope things work out for you.
I just re-watched this video. Noticed you ALSO installed an aluminum driveshaft, was it from a 4th gen? And how was the fitment like? It is on my list, post LS swap. Thanks, love all your videos.
4th gen ALU driveshafts are the same length as our cars- about $100 used. Walter-racecraft sells an ALu shaft for $300 ish mine was from summit for $350 ish
Does a 7.5 3.73 gear drop right into one of these fine? I have a 1997 Firebird 3.8 with the 3.06 gears and want to swap them out for. 3.73’s or even 4.10’s. Everywhere I looked everyone is just swapping out the entire rear end assembly with a Z28 or TA WS6, not trying to do all that lol. Other than no traction control, is there any reason NOT to just drop a set of new gears in?
some carriers can't accept lower gears. for example, my stock 2:73 diff can't accept a 4:10. if you want 3:73 you'd have to get a 3 series diff. I'd look for a 4th gen diff with a LSD and 3:42 gears. that will accept a 3.73 or 4.10
@@3rdGenGuy in your opinion, would 4.10’s be overkill for a four speed auto and 200hp/225trq? I just want a fast 0-60, 0-80 and snappier throttle around town 0-30, 30-65 and that’s it. I’ve always had V8’s with at least 315ft/lbs.trq and V6’s are completely new to me. Let alone a late 90’s V6 lol
@@3rdGenGuy I also got the car for not much money and want a quick city car so I don’t want to drop a LS1 or 5.3 in there lol. Minimal mods, gears/tune, intake lid and exhaust and that’s it. Maybe a moderate cam with better low and mid range torque at most.
the 4:10s and an automatic will kill highway fuel economy, but will be fairly quick out of the hole. usally automatic cars use 3:73 and the t56 boys 4:10s
Your videos are great. I have a question though, I see you wedged a rod in there to get your posi unit out. I did the same thing but mine just won't come out. Am I doing something wrong? Do I need to do something else to loosen it free?
7.5in 10 bolts hold about 1.8 quarts. the easier way to make sure, is just to get the axle level, and keep filling until oil flows out of the fill port.
$157 for a primer and top coat in just plane OEM Black. only thing i had to do was use brake cleaner to get rid of all Oils inside the axle and tubes. fairly easy, took 1.5 cans of brake cleaner.
I just want to say thank you for all your videos and continuing to make them. they are great info!

Great video man! It was very helpful for me rebuilding my stock GM 7.5 10 Bolt.
Awesome video ! I have a gm10 bolt diff as well and it’s cool to see a well put together, video of it thank you👍🏽 hope to see some more
You probably wont see an assembly.
i'm simply not qualified to show that.
but we'll see what happens
You're my guy for this thank you
Another great video!! I have a 92 Z28 which one day I may have to do that as well.
very detailed thanks

@@3rdGenGuy Yep, that's where I find em as well. Any reason you didn't go with a used 4th gen shaft instead, if I may ask?
Do you have a video of the rebuild and what pets you used, do you have a talk thru that would be very helpful
i don't have the tools to rebuild an axle, so i had a shop do it.

if the axle tubes and bearing caps are removed, it should pop out.
MOAR power i guess.
@@3rdGenGuy lol my man! Alright. Power it is!
How many liters does the differential carry?
7.5in 10 bolts hold about 1.8 quarts.
the easier way to make sure, is just to get the axle level, and keep filling until oil flows out of the fill port.
What did you put back in the rear end. ? What parts did you use ?
list of parts I used s at 6:32
Just curious after the rebuilt how much power would it be able to hold after??
Probably the same as before ha ha.
nothing can really make a 10 bolt stronger due to how tiny the design is.
@@3rdGenGuy i was really hoping to hear 500wheel torque lol
@@alex13238712 mrgetinthere has a video on how to make the ultimate 7.5
Any tip for stuck axles? Or do I just keep beating on them lol
they should just come out. unless the C-clips are still in.
I'm doing the same thing. How much did it cost to powder coat it? thx
$157 for a primer and top coat in just plane OEM Black.

Your modification list at the end is covered up by a preview videos.
good catch. i fixed it.
I now understand why a reman cost $1200 bucks
