All the clamping force from tightening the bolt is on the bushing sleeve though. So when the control arm rotates, if the sleeve is clamped in the mounting bracket, how is the sleeve pivoting around the bolt? The sleeve is clamped, the bushing is press fit in the control arm, the bolt isn’t rotating, so the only place that can move is the interface between the polyurethane and the sleeve. If the bolt were the pivot point the sleeve would start cutting into it and it would loosen up. Metal on metal isn’t a good idea especially if it’s in a dirty environment and the tolerances aren’t tight. The bolt is there to provide clamping force which is why you replace them once you remove them.

@@dirtyaznstyle4156 that's not true, you don't grease the friction face on the not and bolts, they clamp they the mounting point, and with grease on the bush and the correct torque spec the whole bushing spins and keeps position, whilst the clamping force on the ungraded bolt and nut it enough, that's why not having correct torque spec is a huge issue

@@hardlinefoil7532 the polyurethane is press fit into the part though, it’s not supposed to move. If it were a rubber bushing the outer shell is press fit into the part, the sleeve is clamped by the bolt and the rubber flexes when there’s movement right? Same with the poly except the poly bushing doesn’t flex and the sleeve rotates inside of it. If the poly is pressed into the part and the sleeve is clamped in the mounting bracket, when the bushing rotates neither component is going to move. Movement happens at the smooth interface between them. Tightening bolts at ride height isn’t really an issue with poly bushings because of that. All major suspension fasteners should be graded bolts. The control arms, leaf spring hangers/shackles, and shock mounts on my truck all have grade 10.9 bolts.

I'm sorry I'm just a hobbyist

Mature plants that get some afternoon shade seem to flower alot. Most cacti take several-many years growing in the ground before they will flower.

@@AZsmoothrider thanks 4 fast response 💜

In theory, sure. But weeds will still grow eventually because enough dirt will blow into the rocks. The video was aimed at people who still have plants or trees. Or who may want healthy soil.

@@AZsmoothrider Okay so it was aimed at folks who have vegetation in the ground. But what if you don't have vegetation and don't plan on it in the future? I can tell you from experience this stuff works! Yes, dirt will blow into the rocks ON TOP OF the barrier and cause weeds. For that matter it is impossible while installing it to keep dirt of the top of it. However, once in place with a nice layer of rocks the weeds with be very few and very far in-between. Additionally, when they do pop up it's a simple matter of reaching over pulling them up with the greatest of ease as they are NOT rooted in the soil they are just growing in the small amount of dirt that made it's way in-between the rocks. They are so easy to pull out an infant could do it. And for those who don't want to bother with even bending over pull out the minute amount of weeds that do spring up there's always a quick spray with a weed killer. Especially in the hot sun. Hot sun+weed killer works like a charm fast. I walk my suburban type home pretty much everyday just to look around and enjoy but one doesn't have too with this stuff and rocks in place. You could go a couple of months at my house, walk the rocks and it would take you maybe 10 whole minutes at that getting the very few weeds out.

Yeah, don't over water (it's easy to do, and they will break in the wind) in fact they really only need supplemental water on either side of monsoon. Over pruning will cause rampant growth and more breakage. These naturally grow to short and squatty touching the ground. Less you do the better imo.

Flowmasters in winter with salt I get year worth out them lol

I'm pretty much against any and all underlayments or landscape fabrics. You will still get weeds and the fabric will eventually start poking up and turn into a mess. But to each his own.

@@AZsmoothrider I hear you and realize some weeds may grow but have to use something so small rocks don't dig and sink into soil. So what be best to use?
