Not long ago I was pulling my pontoon out of the water and 4x4 wound not engage. Transfer case engaged but front tires did not. Any ideas?

Also, I need to have rear rotors turned. How difficult it is to remove them?

 

IWE Solenoid. My truck had the same problem, replaced the solenoid and the problem was gone. Solenoid cost me $17 shipped from rock auto

 

If that's the one behind battery on fire wall, I changed it and it's still the same. No noise from front end, just not engaging.!?

 

get yourself a vacum pump from autozone...cost about 20 bucks or so...i was having problems with my 4 wheel drive not engaging on my 05fx4...with the help of my autozone vacum pump...i narrowed it down to a bad IWE...not to hard to change....if you go slow...its a 3 beer job...

 

That's what I was thinking the problem was. Vacuum looks good on both sides. I think my iwes are froze in the unlock position. How much are they normally?

Another thing to try before replacing parts; try tapping on the shift motor with a hammer handle etc., (it's on the transmission, top-front), an electric 4x4 engagement motor on ALL 4WD F-150s in our group. The shift motor sticks if not used often (it's similar to a starter solenoid sticking).

 

He said his TC did engage / shift - which means his problem is either the solenoid or the IWEs. Since he said he replaced the solenoid, that's probably out too. So that leaves the IWEs.

Like somebody else said, get a vacuum pump and test your IWEs. Check this thread out: https://www.f150online.com/forums/20...then-some.html

 

Thanks RUSTY06CREWFX4. I checked autozone and they quoted $119 a piece.

 

2stroked-I stand corrected.

OP- You might want to check that vacuum operation of the IWEs before spending a bunch of money. They normally are in the "engaged" position unless vacuum pressure is applied to dis-engaged them. One of mine failed in the engaged position (broken internal spring). Read through the thread 2stroked posted...

If it is the IWEs you can save a lot in labor replacing them yourself.
