Easy to install and fixed my issue for now at least, its been a month so far.2016 F150, I was getting a grinding from my front end in cooler weather at speeds between 20-40 mph going up-hill. Was very intermittent and could only replicate on two stretches of road near me. When letting off the accelerator or selected into 4H the grinding would stop. After reading around I found this solenoid or check valve could have been the culprit. Changed both as they came together and has fixed the issue.

I was hoping that this would solve my IWE issues. It did not. I can't say that this works any better than OEM or just as poorly.

Purchased this part in February 2024 and it failed. End of September, IWE started grinding like nobody's business (Loud). Finally figured this parts failure was the cause of the grinding. Was attempting to engage four wheel drive with driving and upon acceleration. Others may not have had the part fail, but the purchased did

Had it for almost a year. Works great. Only thing is that didn't work was the hose length was way to short. Had to fabricate with old hoses.

Cleared up the issue of hubs not disengaging. Cheap solution to start with if you have hubs that are not totally disengaged when 2wd.

3 trips to the dealership and no fix. A quick 2 min search on YouTube and found out it was likely the check valve. Pulled to check and replaced the faulty valve.

I had my 2020 f150 in the shop twice to find and fix an awful grinding in 2wd that would stop in 4h. Couldn't find a problem either time, even though I asked them to check this. Well I ordered this part and had my truck fixed in 2 minutes, impressed my husband! Was exactly the issue.
