Expert:  Jason replied 4 years ago.

You either have a bad fuel injector, or bad compression.

Start by getting a compression reading of at least 3 cylinders, including #1 (which is passenger side, front cylinder)

Customer: replied 4 years ago.

I will check compression. Runs fine when cold then when warmed up 10 minutes later ( freeway run, exit, back on freeway) before i get back home it's missing like running on 4 cyclinders. So no way igniter from your experience.

 

 

Thanks,

New question Jason,

2001 Toyota Sienna V6 3.4 Liter

 

Right hand drive shaft assembly removal/passenger side. Everything is removed, axle nut and big circlip, ball joint bolt, and tie rod bolt. Will not come out even if hammered. What is the trick. Axle side from rotor is already cleared and out. But when I pull the inboard joint won't come out of the isolator/motor mount bracket.

 

I removed the bearing lock nut. and hammered out inboard axle to the passenger rotor side from big circlip and it won't budge. Says after removing big circlip remove axle, right where big circlip is at. It will not move.

 

When I pull the axle outboard shaft, from rotor side, the boot at the inboard axle is stretching, like it wants to break away and the piece that should come out is still in the isolator/motor mount bracket? And it's not my first rodeo either. I have changed some front CV joint/axles before.

Any ideas?

Thanks, CT

Trying to remove whole RH side passenger axle shaft from van (inboard and outboard CV's attached to axle) but won't budge even after big circlip removed. Even tried hammering out to rotor side but won't move. From what I'm told, after big circlip is removed from isolator/motor mount, slide shaft out toward passenger side but won't even budge.
