I’m a DIYer and love working on equipment and I’ve got a two-part question: are there particular jobs that home mechanics mess up that y’all end up having to fix later? If so, what things are usually wrong with what the DIYer did or missed that they should have done or should’ve done differently?
Brakes and wiring. I see a lot of electronic parking brake issues. As for wiring, I see poorly done aftermarket sound systems and LED conversions. Owning a set of torque wrenches, a multimeter, and a service manual will solve some issues. Don’t get me started on lowing and raising ride height without any understanding of suspension geometry.
I don’t own anything with an electronic parking break, but they don’t seem that hard to deal with. What’s the usual issue (or is there one) with LED conversions?
The suspension one made me laugh. I literally have looked at so many lifted vehicles that I could even tell were wrong without a trained eye. I’m pretty nervous to mess with lifts, differential ratio changes, etc. at home. I took those to a good shop. Can’t beat decades of experience, no matter how “interested” in those things I am.
