This mechanic solves major issue in early 2000 GM trucks like the Silverado and Tahoe

GM trucks have covered millions of miles of American turf over their many decades of dominance on the road.

From the 1960s C/K to the new 2026 Silverado, countless models have been spun off the General Motors assembly line.

But between 1999 and 2006, many of the iconic trucks had a major issue, and if you didn’t have greasy hands, you’d likely have been charged a few bucks by a local garage to fix it.

However, TikTok user and popular mechanic Andrew Parker (of Whistler’s Auto) has come to the rescue for people still using them.

And, it all stems from a dry shaft issue in the steering column, described as making a ‘ugga dugga thugga’ noise.

Taking to his TikTok channel, Parker revealed that the steering column gets very dry in these vehicles and needs a bit of help to be greased up again.

“The column gets dry. You literally have to re-lubricate it like you’re pumping a pump jack,

The fix is easy enough, though.

All you need to do is disconnect the dry shaft and pump it back up 10-15 times towards the steering wheel. Then, the grease will lubricate it, and the noise will disappear.

New cars mean new issues, though

Nowadays, the GM trucks like the Chevy Silverado are much more advanced, and this dry shaft issue shouldn’t occur.

But that doesn’t mean the cars are easier to fix when issues do crop up. In fact, one old-school mechanic nearly hung up his wrench and overalls after taking a look under the hood of the latest model.

Thankfully, the Silverado typifies the robust nature of GM trucks, and they usually bounce back to life even in the harshest of conditions.

And when all else fails, at least the new fleet comes with a brand-new personal assistant.
