Well, Suspension is now all done. runs like new truck. BUT Money light came for misfire and I have bad O2.
FYI, This job was harder then any suspension work. There is just no room for B2S1&2 to work on, If you missed first time your are done with Nut and will round off. Of course I used O2 tools like fours of them and all are POS and didn't work out, Yes, I PB'ed the hell out off for two days. Long story short I ended up removing the exhaust manifold. Some folks may be lucky but, I run out of luck on this one. FYI to take out the eight nuts 15mm three on each moniforld and two on the exhaust end. You must take out the skeetplat otherwise there wont be any room to take out the manifold, those bolt are 18mm. Two bolt and nut on each side. You may need three hands on this job, some help was warranted. anyhow, put torch and wise gribs on last two cut the wires long 22mm socket with impact and job was done. don't forget apply moderate amount of copper anti seize to the threads. PUtting it back you need to lower the driver side manifold in order to push it in place were exhaust meets.
Keep an eye on gasket on driver side manifold, I lost it while installing it, and had to do it over.
I used NTK O2 same model for all four sensors.
3/8 tools didn't even fit the Nut. garbage
