Question about 2001 Ford F150 Styleside SuperCrew
2001 F-150 4wd 5.4l engine. Around 55mph it feels like the rear wheels are slipping. It feels like a slight surge or ****. It happens a few times in a row then stops, then will occur a few minutes later.
First of all, do you have an automatic or manual transmission?? Cause if you have a manual tranny and only the rear wheels slip, then the problem should be in the rear differential. If you have an automatic, the valve bodys in the the tranny and a few other parts in there and in the transfer case may malfunction causing the the tranny and/or transfer case to switch from drive to neutral a few times fast. Also if you have an automatic tranny, start by checking ALL the oil levels in the tranny and transfer case cause any fluid missing might be enough to cause loss of pressure and cause such a problem, in which case just toping it off will solve the problem. Always good to check the transmission oil filter in the auto tranny cause a bad filter might cause clogs that will also give the same problem. If everything on the tranny and transfer case side is OK, then again the problem is in the differential. Also one last thing to be sure of is that the front and/or rear differentials have never been replaced or their ratios changed, cause if the front and rear differentials have the same ratio, or close enough to the same ratio, it will cause some weird skipping/slipping problems. That's why engineers make the front and rear differentials with different ratios.
