1969 Chevrolet CST10: Part Deux
The gist of the build so far for those who are new to the site:
Quote:
The Dash Pad Gauges Now it's blingin' inside! Drive drive drive, come last thursday night, a hidious grinding appears. It's like rocks being chewed up by the rear end. But for the life of me I couldn't figure it out while driving. Not the diff, it drives fine. Lugs are all tight... Drive shaft has no play... Trans shifts fine. It hits again, and once more, nothing appears wrong. I get home, double check everything, nothing's apparently wrong, and goto bed. Next morning, drive into work, no problem. Birthday night, on the way out into Houston for some shenanigans, and the violent rock crushing sound reappears, this time with much more frequency. Enough to make the truck pull left when it grinds... WHEEL BEARING SHYTE! In theory, a wheel bearing on these older axles is a pretty **** simple job. Pull diff cover, unscrew the lock screw for the spider gears' shaft, remove shaft spider gears, pull axle clips, slide axles out, and knock out bearings. So, get to the diff... Look for the lock screw... ****. It's been broken off, and someone has already tried drilling it out. Sonuva*****! The entire axle is locked together by this simple screw. So in effect, my uber badass indestructable Dana 60 is scrap iron due to a $15 wheel bearing and a broken screw. Not to mention it's one of the rarest axles on this generation of truck, the 6-lug Dana 60. Having no choice, after breaking more drill bits and even stripping out easy out bits (it's a hardened steel screw I might add), I have no choice but to pick up another axle. On to the GM Coporate 12 bolt! One of the strongest GM axles at the time, but no where near as beefy as the Dana 60 (Once I pull the 60, you'll see). Thankfully it's in **** solid shape inside, and came apart with no problem... Besides that the bolt that holds in the spider gear shaft also was broken! But, it was sheared at a 45* angle, so it was able to thread out almost all of the way, and I was able to get it out. Perfect fit in the back of the Jimmy! FUUUUUUUUUU- One of those times where it would be nice to have a cop light and siren. And the new GM 12 bolt, 3.73 open diff axle. It's not all bad, I was wanting to put 3.73s into the truck later anyways to help with freeway cruising (80% of my driving where I live), and it's an excellent balance of power and economy, even better when I swap in an OD trans later on. Nice and clean, even if it isn't as monsterous as the Dana 60, it'll get any job done I'll ever need. And in under 30 minutes I had both axles out, and both axle bearings out. See how god **** easy this would have been if someone else hadn't ****ed up their job when they replaced the ring and pinion on my axle? Oh well, the surprises you find in a 40 year old truck. The plan is to keep the D60 around and tinker with it. It's the OG axle and a very rare one for the 60-72 Chevy/GMC trucks, so it has some value compared to your dime-a-dozen GM axle. Maybe one day I'll have the heart to just torch it apart, but don't have the time or tools for that now. Tomorrow it's suppose to rain sleet and be generally ****ty, so I'll rebuild the axle and paint it, and hopefully friday swap them out. Maybe now my speedometer will count right too!

Texans legendary money pit. I absolutely LOVE that truck. The orange truck lowered with black wheels make it look so mean! So aggressive! Back when trucks were trucks. Once you get the axle perfect, then get the new cab on, and no more problems arise what will you do with your life and extra money?

There's always the quest for more speed
Or buy another old car, start all over again.

Why risk the truck for speed? Do a V-8 conversion of a Chevette to start over. They'd make a good pair, a V-8-ed Chevette and the CST/10. And nobody would expect anything of the Chevette!

Why not? Nothing wrong with horse power if used properly. Not talking about a stripped out race truck, but something more than a little 300hp 350.

Gearhead- it's a small screw that's recessed deep in the carrier, nothing worked.

Gearhead, the only way he's going to be able to take that Dana 60 apart is by cutting the axle shafts or possibly the pinion gear retainer if he can get to it. |

It was a problem in their computer, it had the wrong part number. The part number online pulls up the seal for the Dana, but that same number instore pulls it up for the GM axle. The difference in OD? .01 of an inch! Always bring the old parts to the store, compare **** before you leave.
Other than that, NAPA kicks ***. Had everything I needed, knew WTF I was talking about, and actually had things in stock... Walked out with everything for under 30 bucks too, good bit cheaper than it shoulda been. The same can't be said for Vatozone. Anyways, got the right seals and got to work this afternoon. New bearings in, new seals, diff sealed up (it's an interesting game getting those spider gears lined up), and then jacked the truck up to rob it's brakes. Boy. Drum brakes... 1st side took over an hour and a half to take off, and put on the other axle. I've never messed with drums and hope to never have to again Thankfully with drum brake tools, getting the springs on wasn't too hard, but it's a PITA never the less to get everything setup 1st. Tomorrow the axle goes in. Ran out of light here, it's cold, and I need a burger. Ready to rock and roll once more! I had to start the truck up and listen to it for awhile. Tired of driving our quiet little '98 GMC Jimmy.

Why dont you go for discs? Better braking power means you can hold the throttle for longer. Is this your final axle or did I miss anything because I'm being a bit lazy at the moment?
My dad has had a VERY good time with Advanced Auto Parts. His former coworker from Best Buy became their CEO, and he shops there so often he is given a special discount. I'm going to take advantage of that discount once I get my car. Although the main difference is that I will be economy driving, not power driving. |

I hate advanced autoparts the one were I live the people don't know what the hell they are talking about. Sorry to here about the dana 60 id love to have one. Napa does make great parts but were I'm from they jack the prices up skyhigh because they have no compitition. On another note did you put that new motor in yet? Because I got some high comp pistons if your interested made for the 350

The axle is in, and everything but the drive shaft and panhard are hooked up. I didn't think about this in retrospect, but the D60 is technically a 3/4-1 ton axle, and it had the heavy duty drive shaft accordingly. So when it came time to bolt on the driveshaft, U-Joint was too big!!! Gotta two-sized u-join (again, Napa, you kick *** at finding this, they're **** hard to find) that adapts the 3/4 ton drive shaft to the 12 bolt (which is the strongest GM axle from the time, funny). Haven't put it in yet, but will tomorrow night when I get back home. Pan hard bar won't line up with the new axle, the stud on the axle isn't long enough, and the pahard is too far towards the rear. Will have something rigged up tomorrow, trying to hunt down a different sized stud tonight. Should be back in bidness tomorrow.

very nice grab and swap. took you really no time at all. me and my dad are gonna be picking p a set of axles on monday(dana 60 front and dana 70 rear) for cheap, and its a shame to see a broken screw ruin and good axle but at least you got a new one.

It was more work than it should've been, especially with the panhard bar, can't see why it was so far off.
But, it's done and on the road. Had there not been a parts problem this would've been done in no time.

i second that. ive never had a big problem with them either. the napa people around me tho are really bad. and the parts are always like twice as expensive too. i guess the service and such ranges from area to area.

Up here autozone sucks ***.... We were trying to find a master brake cylinder rebuild kit for the golf cart and we walked in there and the guy don't even look at the part number book, he just tells us to tell him when we find it..... We just got mad and threw it back, then left... But luckily napa had it, even in stock, but there's this tall mexican dude in napa that is great help?

Welp, besides the further consumption of dino-juice, 3.73s were a good choice. Though, lesson learned, don't rely on online calcs to measure gear ratio. Despite the factory options of 3.9x and 4.1x, someone threw in a 3.50 rear gear (presumably when they broke the screw too).
Oh well, so **** it, the goal of better fuel mileage was silly anyways. Sucker moves pretty well with 3.73s in it though. And when I get the OD trans, a shorter rear tire can go in, and this thing will certainly be much quicker off the line. Also, the interior as it currently stands, all chromed up (as it was originally for the CST trim) and the dash is done! And the new, albeit smaller, GM 12 bolt
