I just went through this. Check all the usual suspects first...loose heat shields, exhaust connections, etc. A good way to trouble shoot is to warm up the 4runner to operating temp and get someone you trust to sit in it with their foot on the brake and the trans in R and listen for where the...
I'm ok with trimming a little in the front. My concern was trimming in the back of the 4runner near the rear mud flaps. I'm willing to take the mud flaps off, but don't want to trim on that part of the rear bumper.
You had nothing rubbing or needing a trim in the rear?
I mention 06-09 because the fender flares changed and may make a difference. Are you able to fully stuff the 33's in the rear fender without rubbing? I know the rear mudflaps will need to be removed but I do not want to start cutting the plastic back there. I hate rubbing and if this size is...
Tacoma rear shocks are not designed for the specs of a 4runner. Think about how light the bed of a tacoma is vs the rear of the 4runner with all of the extra metal and glass. Do yourself a favor and get 4runner specific rear shocks.
Looking at your avatar, do you have a full length aftermarket roof rack on it?
I installed one on my 4runner that caused the sunroof to rattle. Once I took it off, the rattle went away.
The 4th gens have about 19" hub to fender front and 21" rear. The kits being shorter in the rear still give you about 1" taller rake in the rear after lift. If you want a little more, you could always add the 10mm OME spacers or ironman offroad has custom sizes that are a little bigger.
Try servicing the pads if you haven't in a while (clean and lube pins and check springs on front calipers). I resolved an issue that sounds a lot like yours this way.
It wouldn't be surprising if the OEM actuator is made by Aisin as Toyota owns them. I would go with whatever I found cheaper of either OEM or Aisin only.
They tried to give you as much "in spec" camber as possible to get you closer to spec on caster. I don't think this is good. If you have a more aggressive tread pattern tire, you will notice the outside tread lugs beginning to feather over time even rotating every 5k. Ask me how I know.

Installed these for less than 100 miles. They were a little too tall for what I needed. I will ship these CONUS for $150. Will work for 4th or 5th gen.
