What to do if your front differential is not working?
What to do if your front differential is not working?
When diagnosing a front differential engagement problem, manually check the vacuum motor first. It’s easy enough to access the motor for testing with a hand vacuum pump. Inspect it for damage, as most vacuum motor failures are due to road hazards.
What kind of body does a Ford Ranger have?
Ranger featured body lines that mimicked those of larger F-series trucks and a flagship LTD, later known as Crown Victoria. With flat surfaces and straight edges mated to a characteristic front grille and headlight design, it looked as a scaled-down F-150.
When did Ford stop making the Ranger truck?
While Ford was planning to unveil the fourth generation, the recession of 2008 put a stop to these efforts. Instead, they have dropped the Ranger and focused on F-series trucks only.
What kind of drive does a Ford Ranger have?
Just like in the previous generation, the rear-wheel drive configuration was standard, with an all-wheel drive as an option. In its third iteration, the Ranger received only a mild visual update, with outer design being similar to the old version.
What kind of front axle does Ford Ranger have?
This means you can’t just install a Dana 35 housing from a 1995-1996 Ford Explorer in your 1998 and newer Ford Ranger. Some people grease the live axle front hubs on their 2001-2011 Ford Ranger by removing the abs sensor, and pumping grease in to the hole.
What is the gear ratio on a Ford Ranger?
The label is similar to the one found on the Dana 35 TTB Axle beams of the 1990-1997 Ford Ranger: The sticker will list the gear ratio across the top (second from the right). If you look closely, you can see that this sticker indicates a 3.55 gear ratio (this sticker is from an Explorer Dana 35). Below the yellow section, you will see ‘F87A’.
What are the front brakes on a Ford Ranger?
The 1983-1994 front brake is a single piston caliper with slide pins. In 1995 the caliper was upgraded to a dual piston (2-piston) caliper and the rotor was upgraded to 1.023 inches thick. The caliper bolts to the steering knuckle and does not use slide pins. The 1983-1988 axle beams are different than the 1989-1997 beams.
Where are the hubs on a Ford Ranger?
The 1998-2000 model had PVH hubs (Pulse Vacuum Hubs), but from 2001-2011, it was a live axle setup. The front axle shafts from 2001-2011 are permanently locked to the front differential.
Where is the viscous coupling on a Ford Explorer?
Here’s a quick ditty about the viscous coupling: Ford first introduced the viscous coupling in the 1997 Ford Explorer and Mercury Mountaineer AWD vehicles. The viscous coupling is a completely sealed torque distribution device located inside the transfer case and is connected to the front and rear output shafts.
Why is the transfer case not shifting in my Ford 4×4?
These motors do malfunction on occasion and are the most common cause of the transfer case not shifting. The relay modules behind the dash also malfunction and will sometimes melt the harness connector at the yellow and orange wires that feed the shift motor.

Where are the vacuum ports on a Ford 4×4?
Ford has used three types of vacuum-operated automatic locking front hubs: pulse vacuum hublocks (PVH), constant vacuum hublocks (CVH) and integrated wheel ends (IWE). PVHs and CVHs have one vacuum port that pokes out at the top of the steering knuckle, while IWEs have two ports located in the knuckle right above the halfshaft.
How to fix Ford Superduty 4WD hubs problem?
Check my video for how to do this in detail. You will completely bypass the electronics of the 4wd system and apply direct vacuum to your hubs. If you have no leaks in the vacuum lines that go out to your hubs from the solenoid, then the vacuum pump should shut off in under 45 seconds (once it fully pressurizes).
