After a particularly nasty freeze-thaw cycle here in Michigan, the roads are destroyed and I need new shocks on the rear of the tow vehicle. Go figure.
I installed a pair of Gabriel Ultra on the rear in March 2016. After almost two years and roughly 34,000 miles they crapped out. I don’t know if the dampening system was shot, but the mounting bushings on both top and bottom were completely torn away.
At the top mount, there’s two rubber bushings that are clamped down either side of the vans mounting bracket. The top bushing on both shocks was completely gone. The shocks were basically just banging around back there. No dampening. Pot holes at highway speeds were treacherous, the back end would hop all over.
2 years/34,000 miles doesn’t seem like much, but whatever. I bought Gabriel’s because I like the name. Besides, they got a lifetime warranty. The only problem was changing them out in 25° weather. But, it’s an easy job.
This time I picked up some washers to fit inside the lower bracket against the rubber bushings. It looked to me like if there was some lateral support it wouldn’t fail so easily.
I pride myself on maintaining a very rigorous service schedule on our Chevrolet Suburban. It’s not only our trusty tow-vehicle, but it’s our daily driver. The manufacturers recommended service schedule are, in my humble opinion, the lazy-mans-maintenance and guarantee for increased operating expenses. So, it didn’t surprise me that cleaning the MAF was not included in the “heavy-duty service schedule”. Never-the-less, keeping this little guy clean is important.
It’s easier than changing the air filter, and every bit as important. On the SuperBurb, it consists of loosening two hose clamps, then removing the assembly. I’ve got the three volume CK8 service manuals, but you can YouTube your vehicle for instructions, I’m sure you’ll find it.
Once it’s free, I used a liberal amount of “CRC Mass Air Flow Sensor Cleaner” to make it sparkly clean. $8 at O’Reilly’s, AOT a $165 replacement part.
Idles much smoother, and isn’t hesitating from a stop. Bet my MPG just bumped up a bit, too.
