easy disc brake swap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

JJR · 01-07-2003, 02:40 PM

dream68 can you elaborate on the 88 truck you got the parts off of. Was it a 1/2 ton or 6 lug 3/4 ton? I have Hollanders on my laptop and would be able to post some info for folks. Hollanders does show the 67-70 vs 71-87 3/4 ton lower control arms being different. Which did you use? I have heard you could use the 88-91 3/4 ton 2wd 6-lug rotors on 71-up spindles using 71-up calipers. I went to Autozone and had them pull a 71 1/2 ton 5-lug rotor and a 88 3/4 ton six lug rotor and they were basically the same and appeared to use the same bearing.

JJR · 01-07-2003, 04:42 PM

Hollanders shows two spindles used on an 88 c1500 2wd. One for a 1" rotor and one for a 1 1/4" rotor. The spindle for the 1" rotor came on 88-91 c1500 and had a 1 1/4" inner bearing surface diameter. The spindle for the 1 1/4" rotor(which is probably what you have) came on the following:

This statement makes for some confusion: This arm (71-up) may have two different ball joints one being light duty, the other being heavy duty. I am assumming they would be different diameters.

I hope this info helps.

JJR · 01-08-2003, 08:23 AM

That is good to know Crazy Longhorn. The local pull-a-part tends to have a good selection of 3/4 ton trucks and occationally an 88-up. The get $15 for control arms and spindles. I have also seen several sets of 88-up spindles on e-bay go dirt cheap. People put drop spindles on and basically give away the old ones. Since a already have a set of 71 1/2 ton control arms and spindles and new ball joints for them, I will probably end up buying a set of 6-lug rotors and use what I have.

ChopTop · 01-05-2003, 05:43 AM

So what you used was an 88 and up spindel? with which lower balljoint, the 88 and up half, or the older 3/4 balljoint. All this utilizing the older upper control arm using the halfton balljoint?

Definetly feel the 6 lug updated adaptation may be within reach here using the newer semi-floating 14 bolt rear.!!!!!!
(light 3/4ton, - 2500 series)

ChopTop · 01-05-2003, 02:16 PM

I wonder if the 76 3/4 ton lower arm with do? Thats whats under mine now. I would love to try this setup. That would give me more reason to re-install the older style upper arm with new bushings. Is this going to change my track width any??

ChopTop · 01-05-2003, 07:44 PM

I don't think that is going to provide you with enough fluid volume for the calipers.

ChopTop · 01-05-2003, 08:24 PM

71-72 I think would be the best, unless someone else has found another one that will bolt on our trucks.

ChopTop · 01-08-2003, 01:15 AM

WHOA!

RON WOODGEARD · 01-05-2003, 05:56 PM

Dream68, Welcome aboard !!!!

That's the way I tried to do it, but didn't know the 3/4 ton was different. A friend gave me 2-1/2" drop spindles off of a newer truck, I bought everything to do the switch, But it came to a stop when I found out the lower ball joints were different, No one around here knew how to get around it. I went to Tuckers in Las Vegas and bought the complete disc brake,spindle kit from them.
Wish I would have known this then. would have saved me about $600.00.

That's nice about a board such as this, With so many people doing this stuff we learn most of the time the easy way instead of the hard way.....

jmanz69 · 01-04-2003, 05:58 PM

You have any pics? I am interested in how it looks.

wnc mountain · 01-08-2003, 05:25 PM

This is great info...but...anyone know if this will work for a 70

wnc mountain · 01-08-2003, 08:42 PM

Thanks, I will have to give that a look. This may actually sway me to go with disks.

70c10 · 01-05-2003, 01:36 PM

dream 69, Welcome to the board from Maryland. This sounds very interesting!. We would love to see some pics when you can. I don't drive my truck enough to justify the $700 kits either but would go for half of that if it's as simple as you say. I'm assuming you used the 88' 4x4 brakes to retain 6 lugs?. Did you use the newer style Master Cylinder and booster? Thanks.....Jim

70c10 · 01-08-2003, 08:45 AM

Cool!, This sounds like the next topic on the FAQ board, hopefully with a few pics!. Thanks guys.

JHickson6 · 01-04-2003, 06:28 PM

Damn thats a good idea, let us know how they perform and wear over time!!! My hats off to you!!

crazy longhorn · 01-05-2003, 02:46 PM

Dream 68, thats an interesting swap! how did the tierods work out with the 88 spindles?(or better put...which ones did you use?)

crazy longhorn · 01-05-2003, 07:48 PM

2nd that chop top......the calipers will hang also with the residual valve on the drum master......

crazy longhorn · 01-05-2003, 08:29 PM

dream 68, i have always been a beleiver in peel the parts off the same truck if you can. My 69 longhorn has ALL the pcs off a 75 C10(master, lines,hoses,prop valve,calipers,reardiff/brakes......yep, its a 1/2 ton ride now! I couldnt say for sure on your combo, but i dont like to mix em. Generally, the pcs that were designed together tend to work best together. Good luck.....crazyL

crazy longhorn · 01-06-2003, 08:21 PM

Thats cool, its sounds like it will get around all the center link/tierod issues that are involved with using the 71-72,or 73-87 pcs on the older trucks!

crazy longhorn · 01-08-2003, 01:48 AM

JJR,the info given to me on the 3/4 tons(from local napa) is the ball joints interchange from 71-86 or 87 on the pickups. I didnt see his book, so it was just info given to me. I do know from experience that the 71 3/4 ton lower ball joint will press into the 67-70 3/4 ton lower arms, but the steer stops are different on the older arms(same deal as the 1/2 tons, it will shorten the turning radius), & will require a little grinding on the stops on the spindles to straighten it up.......crazyL

GMC JUNKIE TOO · 01-06-2003, 11:36 PM

Dream68 youve got me thinking. Chevy made 6lug 2wd 3/4ton truck 88 up, so would the balljoints and evreything still work, I am wondering if the 6lug spindle is the same as the fivelug so i wouldent have to change the rearend.

GMC JUNKIE TOO · 01-07-2003, 01:52 PM

awsome, it will be alot cheaper than $899.00 for 6 lug disc brakes evenafter the drop spindles.

sixnine · 01-08-2003, 01:04 PM

Man, this is the reason I just love this site! This changeover will definetly be on my list of improvements I plan to make over the next 2 years. I'll be enrolling in the Auto-Body program at the local Community College and the instructor said I could use the school shop and tools after hours. Do any of you see any interference issues if I were to use an '88-'95 dropped spindle with this swap? Dream 68.............keep us informed and post any pictures. Great job!

dmurphy68 · 01-05-2003, 01:16 PM

can you post some pics love to see. did toy have to change your lines or power booster just wanting to know. love to do it if i can do it for cheep. the 900.00 kits are not for me
thanks
Darren

dream68 · 01-08-2003, 04:22 PM

OK GUYS: the steering linkage is a tad sloppy in the spindle, so this is what you do. use the 68 intermediate shaft with the 88 tie rods. the inside tie rod end is changed to PART# : MOOG ES2020RL.(tie rod end). This setup fits and looks like a dream with no binding anywhere. the 88 tie rods are also bulkier than the 68 original setup..... I will be in touch with more updates as i go... KEEP ON TRUCKIN MAMA!!!!

My 69 longhorn has ALL the pcs off a 75 C10(master, lines,hoses,prop valve,calipers,reardiff/brakes......yep, its a 1/2 ton ride now! I couldnt say for sure on your combo, but i dont like to mix em. Generally, the pcs that were designed together tend to work best together. Good luck.....crazyL __________________ 69 longhorn,4" chop,3/5 drop, 1/2 ton suspension/disc brakes,1 1/2" body drop,steel tilt clip, 5.3/Edelbrock rpm intake/600 carb, Hooker streetrod shorties,2 1/2" exhaust/ H pipe/50's Flows , 6 spd Richmond trans,12 bolt/ 3.40 gears....

crazy longhorn Fabricate till you "puke" Join Date: Jun 2002 Location: Ill Posts: 9,402	Thats cool, its sounds like it will get around all the center link/tierod issues that are involved with using the 71-72,or 73-87 pcs on the older trucks! __________________ 69 longhorn,4" chop,3/5 drop, 1/2 ton suspension/disc brakes,1 1/2" body drop,steel tilt clip, 5.3/Edelbrock rpm intake/600 carb, Hooker streetrod shorties,2 1/2" exhaust/ H pipe/50's Flows , 6 spd Richmond trans,12 bolt/ 3.40 gears....

crazy longhorn Fabricate till you "puke" Join Date: Jun 2002 Location: Ill Posts: 9,402	JJR,the info given to me on the 3/4 tons(from local napa) is the ball joints interchange from 71-86 or 87 on the pickups. I didnt see his book, so it was just info given to me. I do know from experience that the 71 3/4 ton lower ball joint will press into the 67-70 3/4 ton lower arms, but the steer stops are different on the older arms(same deal as the 1/2 tons, it will shorten the turning radius), & will require a little grinding on the stops on the spindles to straighten it up.......crazyL __________________ 69 longhorn,4" chop,3/5 drop, 1/2 ton suspension/disc brakes,1 1/2" body drop,steel tilt clip, 5.3/Edelbrock rpm intake/600 carb, Hooker streetrod shorties,2 1/2" exhaust/ H pipe/50's Flows , 6 spd Richmond trans,12 bolt/ 3.40 gears....

GMC JUNKIE TOO THE QUICKER FIXERUPER Join Date: Jul 2002 Location: Ok Posts: 615	Dream68 youve got me thinking. Chevy made 6lug 2wd 3/4ton truck 88 up, so would the balljoints and evreything still work, I am wondering if the 6lug spindle is the same as the fivelug so i wouldent have to change the rearend.

This changeover will definetly be on my list of improvements I plan to make over the next 2 years. I'll be enrolling in the Auto-Body program at the local Community College and the instructor said I could use the school shop and tools after hours. Do any of you see any interference issues if I were to use an '88-'95 dropped spindle with this swap? Dream 68.............keep us informed and post any pictures. Great job! __________________ Rokcrln - *"I'm a major car addict so trying to go as low buck as possible is like asking a coke head to use flower to save money."* 1972 C10 Short Step -http://67-72chevytrucks.com/vboard/s...d.php?t=261405

dream68 Registered User Join Date: Dec 2002 Location: kelowna b.c. canada Posts: 75	OK GUYS: the steering linkage is a tad sloppy in the spindle, so this is what you do. use the 68 intermediate shaft with the 88 tie rods. the inside tie rod end is changed to PART# : MOOG ES2020RL.(tie rod end). This setup fits and looks like a dream with no binding anywhere. the 88 tie rods are also bulkier than the 68 original setup..... I will be in touch with more updates as i go...
