Project "YARD" Dart: Chrysler 8 3/4 Rebuild & Regear Scotts Speed Shop

[@williamdavis3509]

Owned and worked on a ton of MOPARS in my life and found the 8-3/4 rearend damn near grenade proof ‼️😂✌️👍🇺🇸

[@seniorrider9337]

William Davis; I have an 8 3/4 with sure lock. It had a leaking left wheel seal and the yoke seal was weeping also. Had a mechanic replace both wheel seals and bearings and the yoke seal. He said the brake shoes were OK and he just cleaned them. I had control issues when braking so I expected the rear left brake shoes were not good. Pulled the drums and yep, the hubs and shoes were "greasy". I noticed that with the trans in neutral, the rear axles turn normally in the forward direction and very hard to turn in the rear direction. Is this normal? Thanks, Tom.

You guys wouldn't believe HOW MANY TIMES I've tried to sell him a proper parts washer.. Awesome video as always!

[@rodney1818]

I don't know this is the internet I bet you a large percentage of people wouldn't believe you no matter what number you threw out there

[@ScottsSpeedShop]

I have no idea what you are talking about Rob lmao

[@theodoredugranrut8201]

Thanks Jed Actually looking at an 8 3/4 with disks for my ole D-100 Central California watching

[@Freedomquest08]

When you get that going, every 4th gen Mustang in town that sees that pink 3rd member hanging down is gonna be following the Yard Dart home, wanting to get busy. :D

[@johnelliott7375]

By hand and I can say that I think I got the right man for the job. Good Wednesday to you tomorrow.

[@christopherstruck7922]

It helped me!! I'm glad I remembered you made the video. Thank you very much

[@moparnut6286]

That's a 741 case are soild pinion spacers OEM? For a 741. I take the ring gear and place it on a induction cook top and set it for 200° ring gear slips right on with gloves on of course.

[@johnelliott7375]

Could watch these for days. But I can only do a couple or I would be in trouble with the boss, lol and great evening to you.

[@stephenhotzjustdriveit]

Thx for the info. I also really like that fixture.

[@peteloomis8456]

Color looks like Farmall Red . That spacer looks like a crush sleeve eliminator which makes setting up the pinion bearing preload much easier !

[@BigfootsnMopars]

Another great video Jed! Thanks for sharing

[@wyattcarlson4547]

One of my favorite new channels!!!! I have a 74 satellite Sebring with a 440 and just bought a 66 dart gt with a 451 stroker I hope you can help me out

[@ScottsSpeedShop]

I appreciate the kind words, if you need help, I can try to help [e-mail] is my email

[@michaelmarks5012]

It's splitting hairs but I was taught to use a dial indicator on the contact point of the ring gear to the pinion. I'm sure that 273 will pep up going up to a 3:91. The great thing about the 8 3/4 is you can "quick change" the gear ration by sliding out the axles & dropping the hog head.

[@Chevyv8man1]

Michael, You're right, you have to use the contact points or the ratio in size will through off your readings by a lot.

[@joew7328]

The ol saying is it's all in the rear end🤣 great vid bro👍

[@paintnamer6403]

I heat the ring gear with locating studs in a boiling pan of water and dropped the sure grip on to it no problem. That was a 1975 9 1/4" I fit with Direction Connection 4.30 gears. It was great in my Fury ex cop car. Your Lawn Dart will be that much more of a neck snapper with good gears.

[@shartne]

nice job. this work will probably turn over the tires now.

[@huck01955]

Nice work Jed .

[@OOFGARAGE]

I want to do the rear end in my 79 power wagon but that mystery box terrifies me man proud of you though I’m proud I’m rebuilding a wiring harness 😂

[@blakenorman4822]

Just got a 741 think it has 267 gears, im putting together a la 360 350 hp, 727, 1 ton 47 dodge panel truck, wanting to take it 2000 miles next year, want it to be able to squeal tires and cruise too, what set up would you recommend in my 741? Thanks for video

[@ScottsSpeedShop]

Depending on your tire size, I think something in the 3.23 range would suit ya fine. A 3.23 gear ratio is based on a 26 inch tall tire, so if you run a 28, then you'll have to scale the ratio accordingly. It's really pretty simple stuff at its core, but if you need anymore assistance, reply to this comment or email me [e-mail]

[@sixpackroadrunner]

Looks good, Jed I hope it helps the yard Dart burn some rubber.

Great job and tips👍👍🇨🇱

[@joshdurrant9247]

Hey Jed you have the same seal driver kit I do! Me and dad build all of our differentials by feel and I can't remember ever having one turn out bad. Keep up the great work 👍👍💪💪😁🇺🇸!

[@redram646]

Hi Scott. I was wondering. If maybe you would know. Will a rear end out of a 85 chysler new yorker / 5th Ave fit in a 65 dart gt with out modification?

[@ScottsSpeedShop]

I wish I had an answer for ya, but I do not, but it would be worth a shot

[@sammylisasmith2104]

Another good video bro thanks

[@MoparMan-ff8fb]

I'm needing a sure grip unit or should I stick with my peg leg set up for my 8-3/4 489 case . it is like yours a peg leg but mine has 3:91 gears and want to swap over to 3:55 . ive never changed out gears before . would be great if some had a reasonable sure grip unit laying around for sale ??? mine has the same play in it . paid 125.00 for the 489 . my grand dads always used gasoline to clean parts and nuts and bolts in an open air environment! the case will be going into my project 65 dart

[@ScottsSpeedShop]

Clutch type sure grips are indeed pricey, sometimes it is cheaper and better to just go aftermarket

[@woolyhighlander7280]

Good One Thanks

[@5hatsmedia938]

I have a 8 3/4 suregrip. Just put it in car and with drive line out and it is harder to turn in reverse. Can you help at all.

[@ScottsSpeedShop]

Harder to turn in reverse, hmmm it could be a lot of things man, reply to this or email me [e-mail]

[@Russeljfinch]

Do you have to shorten the axles ? Someone said yes (by 1/8”) .is that right ? That’s a pretty rare gearset nowadays

[@mrmoss149]

" Nuthin' Bertha can't fix". Amen.

[@gregrogers3030]

If you add about six or seven drops of transmission fluid into the air hole of your smaller air impact guns they probably could have loosened the pinion but lol. It’s a little trick I used to use when I was working at the dealership.

[@czehner7157]

slapper bars on a mopar? use superstock springs and a adjustable pinion snubber...

[@ScottsSpeedShop]

Super stock springs are a waste of money, that came straight from the mouth of the legend Herb McCandless, his family all use stock leaf springs and cal-tracs now-a-days. My Dart has a pinion snubber, i just leave the slapper bars on for the look

[@mikestackhouse9001]

Very well done Jed. Now, don't drop that puppy on your big toe when you take it off the engine stand!😁

[@JamesTanner-um3on]

I have a power Lock POS unit can find the right bearings number

[@ScottsSpeedShop]

I just typically order a rebuild kit for either my 741 case, 742 case, or 489 case. If you are wanting the sure grip rebuild kit, check with drdifff

[@MoparMan-ff8fb]

I heard you can use a short bed dodge truck drive shaft in a mopar car like your dart and my 65 dart ? it has to be cut down but suppost to be stout to use in a v8 car like ours? does my 498 case from a dodge 3/4 ton truck have that big U-joint piece?

[@ScottsSpeedShop]

It should have the 7290 big u joint, but you'll have to measure to be sure

[@dartdude2668]

You can just use you car driveline.

[@rodney1818]

I was thinking about previous videos and if she didn't give you problems she would not live up to the name Jezebel LOL is that the same tool you use for back talk as well as backlash

[@zarkeh3013]

9:45 big steel sleeve looks like a crush spacer eliminator! or something to that effect...

[@garryhatchett775]

I tried setting up my 3.55:1 but it whined like sob. Must have done something wrong.

[@kennethdispain1807]

Hell yeah brother

[@jamesseaman6919]

It’s.005 backlash with a centered helix pattern!

[@ScottsSpeedShop]

Good for you buckaroo, I will set up my rear ends how I have always done them, and you can set yours up too tight

[@michaelstrangefranke7002]

The reason your dad didn't want you to mention that he was helping you is because he didn't want anybody to know that he was working on your pink rear end 😂😂

[@JamesTanner-um3on]

What is the bearings number please

[@ScottsSpeedShop]

I have no idea, sorry

[@jimmyvickery3366]

Dude you need .007 th backlash you need 35in odd turning torque on pinion I hate to tell your going to have problems with that. Not trying to be a smart ass. But I have 42 yrs exp in chry rearends in a dodge dealer

[@ScottsSpeedShop]

Factory spec in my Mopar book said .010 to .016. Rear end is in the car now and it is working great. No howling or any of the bad sounds. Plus if the center chunk was that sensitive that .005 will cause harm, it'd be a pretty awful rear end. I aint arguing just stating my opinion.
