Are you using Crown or Omix-ADA bushings? that would be the problem. Use genuine Clevite, should be stamped in rubber.
I switched from skyjacker leafs with rubber bushings, to BDS 7 leaf with poly bushings. The poly bushings have less 'squirm' and are supposed to reduce body roll and reduce lean when driving off-camber.
I like the more stable feel, but on rough pavement or washboard roads, more of it is transmitted into chassis.
fyi, Most aftermarket shackles have poly bushings. I ended up with Clayton shackles that use an oversize Clevite rubber bushing (have to clearance bumper bolts to fit).

Rubber clevite bushings are designed so that the inner sleeve is immobilized by the bolt and the rubber twists around as needed then returns to resting position. They have to be torqued at normal ride stance (and torqued again periodically as the ride settles), otherwise they will be under constant stress and fail quickly. Poly bushings are designed to turn around the sleeve.

99 Jeep Grand Cherokee stalls while driving
The jeep is 8cyl and I live in Florida so heat index is always up there. While driving down the road at 45 mph the thing stalls for no reason! Just powers off with no warning plus no check engine light or other warnings. Then it will start anywhere from 1-2 minutes later & was 5 or more the other day. Sometimes it stalls at light too but it doesn't discriminate! Fuel pump replaced & injector cleaner is what mechanic suggested since it is at 187K miles but nope still doing it!
So I took it to where they could run diagnostics for codes etc. $100 & nothing! Told my mechanic about Googling cam shaft or crank shaft sensors. He says no the jeep wouldn't crank if those were bad. He thinks it might be PCM but I am gun shy after spending already $500 & the PCM is not cheap.

Ok honestly my guy knows nothing about cars & I know enough to keep me from getting screwed normally (father was mechanic). But I have no clue what to do. The jeep is 8cyl and live in Florida. I had fuel pump replaced, injector cleaner used although mechanic said they look good. While driving down the road at 45 mph the thing stalls for no reason! Just powers off with no warning plus no check engine light or other warnings. Then it will start anywhere from 1
-2 minutes later & was 5 or more the other day.
Fuel pump didn't fix so took it to where they could run for codes etc. $100 & nothing! Told my mechanic about Googling cam shaft or crank shaft sensors. He says no the jeep wouldn't crank if those were bad. He thinks it might be PCM but I am gun shy after spending already $500 & the PCM is not cheap.

So I attempted to remove what I thought was some simple surface rust and discovered the worst thing possible... Any idea how I should attack this? It seems to be rusting from the inside out.

I was worried about that but I feel like if I can force enough bondo into the holes it will fill in the small space behind them and have plenty of support. That still wouldn't solve the rust issue though unfortunately.

Otherwise cut it out, cut a piece a of sheetmetal a little larger, drill some holes in both pieces, and fish it in there. You can epoxy or weld, as needed. Then fill it and sand it and paint it

Looking to replace my driving lights (fogs). I should be looking for 55w or under with stock wiring correct? Would I benefit from doing the "headlight wiring upgrade" on the driving lights? Any good suggestions?

Any suggestion for sheet metal to repair it? Aluminum or Steel? Gauge? Does it really matter? I don't have a welder, so it would have to be riveted in place or I would have to use J.B. Weld or Epoxy
