I have a '99 F-150 sw 4.2. Shortly after the end of the warranty (around 37,000) I noticed gear oil on the pinion flange of the rear axle. Upon investigation, I found that it was not coming from the pinion seal, but leaking through the splines of the pinion shaft, coming out around the nut and lock washer. Ford says I drive it too hard, and the 4.2 does in fact have sufficient torque to destroy the splines inside the pinion yoke, and I should replace it at a cost of around $100, carry out.
Ford motor company didn't tell you that.. Sounds like something that local dealer service writer (who is not a mechanic) is saying..
There are several, more likely, causes for the leakage..
Here's some text from the Ford Technical Service manual on the Rear axle/diff section.
Analysis of Leakage
Clean up the leaking area enough to identify the exact source.
A plugged axle housing vent can cause excessive pinion seal lip wear due to internal pressure buildup.
Make sure axle lubricant level is 9.525 mm (3/8 inch) below the bottom of the fill hole.
If a plugged vent cannot be cleared, install a new one.
A plugged vent will cause excessive seal lip wear due to internal pressure buildup. If a leak occurs, check the vent. Make sure the vent hose is not kinked. Remove the hose from the vent nipple and clear the hose of any foreign material. While the hose is removed, pass a length of mechanics wire or a small diameter Allen wrench in and out of the vent to clean it. Connect the hose when done.
Flange Yoke Seal
Leaks at the axle drive pinion seal originate for the following reasons:
l Seal was not correctly installed.
l Poor quality seal journal surface.
Any damage to the seal bore (dings, dents, gouges, or other imperfections) will distort the seal casing and allow leakage past the outer edge of the axle drive pinion seal.
The axle drive pinion seal can be torn, cut, or gouged if it is not installed carefully. The spring that holds the axle drive pinion seal against the pinion flange can be knocked out and allow leakage past the lip.
The rubber lips can occasionally become hard (like plastic) with cracks at the oil lip contact point. The contact point on the pinion flange may blacken, indicating excessive heat. Marks, nicks, gouges, or rough surface texture on the seal journal of the pinion flange will also cause leaks.
Metal chips or sand trapped at the sealing lip can also cause oil leaks. This can cause a wear groove on the pinion flange and heavy pinion seal wear.
When a seal leak occurs, install a new seal and check the vent and the vent hose to make sure they are clean and free of foreign material.
The guy on the phone claims to be the axle/tranny expert of the shop. My own investigation shows the seal around the pinion yoke is NOT leaking. Upon removing the drive shaft, I found gear oil trapped inside the flange around the pinion nut, which ran out when I pulled the shaft loose. I called a tech at another dealer, who just wants me to bring it in for them to look at for $70/hr. This is the main part I can't handle... If I had money to blow, this would have been the excuse to just rip the whole thing out and put limited slip and a different ratio in. But things just won't allow this.
I bought the 99 SD250 the 1st year model, I told myself...."self, you have never had trouble with Ford before, so why worry this time." Well my truck has been at the dealer over a dozen times in the last 18-20 mos. It still isn't close to being right. Front end, rear end, transfer case, and bad vibrations above 75mph.
They replaced every front end component there is, some of them 2 and 3 times. Still clunks and pops, still squeaks.
Rear end / transfer case:
After the dealer "Fixed" it for the original clicking, it developed a vibration. No they didn't fix the clicking either. After two more trips and a month of waiting they fixed the clicking. Still has the vibration. After several months trying to fix the vibration they now say they will not drive it 75 mph to get it to the point that it makes the vibration. This is after they had already drove it that fast at least 3 times! Bottom line, they screwed it up and can't fix it.
Now the rear axle and/or springs are screwed up. There is a very bad shuttering upon acceleration and it is terrible pulling a load. There is also a severe axle wrap going on, its like they are made of lasagna noodles. I will not even pull my boat right now, let alone my travel trailer.
Now the only good part of this story.
After 2 years of complaining at the service people and service manager, and after writing to Ford customer no-service, I finally got to talk to the owner of the dealership. To my amazement he new quite a bit about my situation. What ticked me off was they were not doing anything on there own to make the "customer job one", or putting "Quality First". I had to keep on complaining.
Finally, they got Ford to contribute $5000 toward me getting a new truck. The dealer is selling the truck to me at $500 over invoice, they say it is only about $200 over invoice, .... RIIIIGHT!
It is true, the squeaky wheel gets the grease. Well not always. I'm still very agitated to say the least. The owner has said that Ford has done this for several people because of problems they have had with the early Super Duties. ???
The 02 F250 XLT, White over Silver, 4x4, V10, SC, 3.73 is due in about 6 weeks.
#133 of 2180 Your getting another Ford???

I had a similar experience with my F-150...I have banished the Blue Oval from my garage permanently!
Could you please provide me a link to that list that you posted from the Center For Auto Safety. I tried to find it on their site, but there was no sign of it.
Also the list says: "Models introduced in 2000 and 2001 are not represented due to a lack of data," then it lists the Tundra at 23 being the Truck with the most complaints. Wasn't the tundra introduced in 2000 and 2001? Should it not be represented?
