    Vibration

    Agree about the balancer. Also check your motor mounts, they could be cracked or totally shot and you would feel vibration. My gearhead buddy checked out my engine a month ago and revved it and said yeah, there is def. a vibration there. He suggested replace the harmonic Balancer, which is an...

    Woo-hoo! I'm legit not a freeloader! Long overdue. TBH, my major issue was with online transactions in general and PayPal in particular -- I made an account ten years ago and never used it but they send me e-mail spam every week it seems. And inertia and laziness. I've learned so much and...

    Heavy vibration at highway speed under load

    Work-wise, it's hard to do live events with celebrities when 1/3 of celebreties' houses just burned down. Work will pick up again. I think my CA unemployment will come in; that's why we pay taxes in this worker's paradise. If so, I am ok with my rent paid and a little time to work on truck...

    Stolen!

    Ah that sux. My '73 was stolen off the street a half-block away from me last year. For some insane reason, they abandoned it 21 miles away, a half-mile from WHERE I WORK. Only damage was a busted window and ignition lock. And the $600 towing and storage charge from Los Angeles ($240 tow...

    Heavy vibration at highway speed under load

    My only real actiion was to replace my engine mounts. One was definitely cracked/torn. That helped some, but mostly I have not taken her on the highway. My car-guru buddy looked and listened and agreed somthing down low in the engine was unbalanced. "Maybe I should replace the thing called...

    Hello from the Netherlands

    My friend, I don't mean to thread-jack, but I had to follow up in case people thought I was crazy. THIS IS WHO I AM TALKING ABOUT Her name is the most complex Dutch thing imaginable even in a country that has been sailing around the world and trading in royal hot woman princess babes for...

    Hello from the Netherlands

    Welcome! I second and third the great color scheme! I had a co-worker in Amsterdam -- he was our "European office" -- fun guy to have beers with, spoke every language ever and told awesome "ethnic" jokes about all the EU countries. You know what is more beautiful than your truck? Anna van...

    Old man constantly asked to drop his truck.Any stock height C10s left in the world??

    Bring that thing to Los Angeles, I will write a pitch today for a NetFlix series about an Aussie bad-a$$ who solves problems and fights crime in his killer C10 that IS AT STOCK HEIGHT and STOCK HEIGHT is a plot point in the first six episodes!

    Old man constantly asked to drop his truck.Any stock height C10s left in the world??

    @tubehead just saw this thread but my first impression which is never wrong: That truck is perfect, don't change a thing! My C10 is low low low. How low? A member of the band War, once complimented my low-rider truck. But if you took Black Beauty to California, people would swarm you...

    Heavy vibration at highway speed under load

    I keep trying, but Hooper's Rear Ends, the good diff shop, keeps bankers' hours and going there on a Friday afternoon when I get off work won't cut it. I know she needs service, work is a little slow now so I need to just plan 2hrs off, drop her off Tuesday at 7am and get a bus to work, go back...

    Check out my rear end

    I don't know how I found this thread but lots of good info here. I have a vibration in my driveline, and looking at driveshafts for a longbed 2WD C10, they are absurdly long. ~73" is off the charts of custom driveshaft shops, actually. Reminds me I have to get down and measure right now...

    Heavy vibration at highway speed under load

    Interesting. I just had a buddy shoot video while I ran the drivetrain up on jack stands. Now trying to interpret what I see. Besides the big CLUNK going into gear, which I see the driveshaft turn 10-15 degrees, which says differential wear, felt the heavy vibration ramp up with RPM, but so...

    Heavy vibration at highway speed under load

    I've had my wheels/tires balanced and rotated, and also had the transmission shop check the flexplate/TC connection and transmission mounts. The differential place was clear: differentials don't cause vibration. (but they will make NOISE, which is just a higher-frequency kind of vibration ...

    Found the oil leak - front oil pan seal or timing cover gasket?

    So, I knew I was leaking enough oil to coat the underside, but somehow thought it was my valve covers which I knew were leaky. I replaced the covers, then did that again while *actually* setting the gaskets right, seemed much better, oil drips much less. Well it's amazing what you find when...

    Heavy vibration at highway speed under load

    DAmn! You caught me! B "Street Takeover" Retty. I will tackle the motor mounts ... which I am not doing today, taking a friend out for his birthday, for drinks at my nice local bar with the pretty young women who are, sadly, it seems, I have concluded after five years, all lesbians. (I love...

    Heavy vibration at highway speed under load

    I had my transmission shop go over my th350 to see if that was contributing. My driveshaft slop is more like +-15 degrees at the diff. I had trans guys: - Unbolt the TC from flexplate and inspect - Re-bolt them after a 1/3 turn shift - Check my trans mounting. - Remove trans pinion yoke and...

    What have you done to your square lately??

    Hey!!!!! That looks suspiciously EXACTLE like the valve cover swap I attempted for the second time last weekend. Oh, looking closer, neither set of yours are completely blackened with oil blow-by....

    What have you done to your square lately??

    Mods -- can we retire this thread? Maybe break off a new one, "What has any mere mortal done to their truck lately?" Amazing work, Sir! For me it's a close race between Inspiration and Shame. ; - }>

    What have you done to your square lately??

    I'm going to try installing my valve covers and gaskets correctly this time. Then I plan to remove a few spark plugs and inspect them to see if I'm getting detonation or some bad misfire at speed. Do I need to use anti-seize when I re-install them, or will they seat just fine back in the iron...

    Love the color. Congrats!

    What have you done to your square lately??

    I decided to replace my valve covers finally, since they were leaking and I was getting more blow-by than Jeff Beck. I can't get to our shared parking space behind the apt building, so I have to street park, but I had scored the killer parking right in front. So I started what I thought was a...

    Heavy vibration at highway speed under load

    I agree, I need to suck it up and get her to the rear-end and differential place. It's not so much the $$$$, more that I need to bethere when they open the rear up and evaluate; hard to get a 1/2 day off work... ;-(

    Heavy vibration at highway speed under load

    The tire and wheel balance helped, but the very heavy vibration at speed is still there. My "hot-rod" mechanic suggested I may be having a misfire -- but that doesn't explain why it's only at speed and under load. I almost wonder if there is something wrong in my third transmission gear...

    Heavy vibration at highway speed under load

    I am going to get the wheels rotated and balanced, order new U-joints (tricky, I think the front is 2x1350 and the rear is a conversion 1310x1350) and see if the transmission shop can get me in to inspect the tailhousing and the pinion/shaft bushing(s). Also need to find a drivehaft shop to...

    Heavy vibration at highway speed under load

    @SquareRoot , My understanding was that rotational slack in the driveshaft meant worn ring & pinion gears in the differential. ETA: also, the condition of noise under load / no noise in coast, incriminates the pinion/ring interface? When useless local mechanic had her on the lift, I thought...
