    What\'s Your Most Common Break Down

    I'm wondering what is the most common breakdown for your K5. Whether it's on the trail, rid'in around or blasting down the hiway. Maybe we can get some of this info together and see if there's a pattern that we can learn from. For the new K5 owners, maybe there are a few things that they should change as soon as they get their ride to prevent their rig from breaking down. Sort of an "experienced" what to expect section.

    I would have to say my biggest problem is u-joints. I change them every six months, and could change them earlier if I got around to it. This winter, I'm using mine for snow plowing so I've had to change them already.

    I would have to say u-joints also. Next time around, I am going to try Spicers instead of the Auto Zone Brute Forces I usually get.

    U-joints, followed by 12-bolt ring gears. My record is 13 busted u-joints in 1 year (One of them even split the yoke on the rear end as it exploded) and 3 12-bolts in 3 years. Haven't had a problem since upgrading to 3/4-ton axles and driveshafts from the 1-ton truck that donated it's Turbo 400 and NP 205 to the cause. [​IMG]

    Re: What\'s Your Most Common Break Down

    whoo.....I'd say we have a pattern...mine's u-joints too. burn through 'em in about 6 months, but i think i might have found my problem last time i changed them. It kinda looked like my driveshaft end had the tiniest of kinks towards the center....didn't feel like seeing if that was the problem & fixin' it then......I should only be a couple months away from new ones anyways....I'll fix it then!!!!

    Next biggest breakdown is probably wiring problems. From plugs just plain falling off to melting off. Wires falling down and melting on my exhaust, and i can't forget all of the splices the dumb@ss who owned my truck last put on it rotting away. When i bought my truck it had 7......yes 7 different trailer light hook ups on it.....and NONE OF THEM WORKED!!!!! took about a year to finally get rid of my taillight problems due to those little bastards......gettin' kinda tired of hot wirin' my truck.

    I'll second the <font color=blue>spark plug wire on the exhaust</font color=blue> problem.

    I have headers installed and the wires on the drivers side loop around behind the valve covers I have. The wires would fall down against the header and the truck would start misfiring.

    I ended up zip tying the wires to the metal brake lines coming out of the bottom of the master cylinder. I haven't had a problem since.

    Short between the ears, followed by u-joints (sometimes caused by the short).

    Re: What\'s Your Most Common Break Down

    Front axle u-joints. Twice in 3 years, I guess I can't complain. Driveshaft U-joints next, once in 3 years. They are a consumable part for every 4x4 the way I see it. Might as well get good at fixing them! [​IMG] Other than that just annoying little stuff, my Jimmy has never left me stranded, but it'll break exhaust hangers, power windows will quit every now and then, you know the little small things that bug you but its not a breakdown.

    Re: What\'s Your Most Common Break Down

    Actually, now that I think of it, it's not life or death, but my rear power window does not work. This also seems to be a common problem with these Blazers, and brought up frequently on the K5 pages.
    Don't get me wrong, I'm not looking at bashing Blazers, just rootting out problems. I love my Blazer and with all the vehicles I've owned over the years, (and there's been alot) it is by far the best I've owned so far.

    Don't forget those crappy dashpads, minor but common.

    Re: What\'s Your Most Common Break Down

    Every once in a while...usually when i'm in a hurry or with a girl, my door won't unlock, aqnd I have to roll down the window and hit the door where the rod is and open the handle at the same time. Also, I blow out my taillight/dash light/headlight buzzer fuse every time I tow my trailer because the wiring is messed up on it. I know its not the K5's fault though, the trailer blew out my friends fuse too when he borrowed it...
