Differentials

I have the exact same thing with a 2002 Mercury Sable GS Not sure but I think it is some sort of vacuume leak somewhere

It depends on the application. Posi is good for straight track racing, or good traction while off-roading, but wears out tires fast on curves and turns.

A central differential for a four-wheel drive motor vehicle is provided on a pair of axles for right and left drive wheels. The differential has a cylindrical differential case connected to a final gear of a transmission, a pair of carriers provided in the differential case one of which is connected to the drive wheels and the other carrier is operatively connected to the other drive wheels. A pair of annular side gears are securely provided in the differential case, and an annular center gear rotatably mounted in the differential case between the side gears. A pair of planetary gears are rotatably supported in the corresponding carrier. Each planetary gear comprises a pair of planet pinions, one of which is engaged with the side gear and the other is engaged with the center gear.

buy a posi differential. it can be welded but it wont last long

I believe that is a 3.55 conventional axle ( non - limited slip )

Check the SPID in your glove box. one of the G** Codes will be the rearend ratio G80 means you have a locking(posi) Rearend.

The Commissioner for Internal Revenue Service is responsible for issuing practice note for the purpose of achieving consistency in the administration of the act 592 and provide guidance to person affected by act 592 (taxpayer) and officers of the IRS.

This allows the taxpayer to know the commissioner's decision in advance. Taxpayers may rely on practice note in determining the tax consequences of their transactions; however, taxpayers must determine for themselves if the facts their cases are substantantially the same as those set forth in the practice note.

Practice Note also act as statements reflecting the internal management practices of the IRS that affect the right and duties of taxpayers. Occasionally they are also used to announce procedures to guide individuals in dealing with the IRS.

On the other hand the commissioner of IRS is responsible for issuing private ruling to clear the question from tax payers where the whole problem and relevant aspects of a transaction are disclosed. In this way the taxpayer is able to plan his business and be able to self asses or project his income for tax purposes. Thus taxpayers who are in doubt about the tax consequences of a contemplated transaction can ask the commissioner of IRS for ruling. It is binding on the commissioner. Where there is an inconsistency between a practice note and a Private ruling, priority is giving to the terms of the private ruling.

The "driving" or drive gear is the source of power or rotation. The driven gear is turned or moved by the drive gear. Example: The pulley on a motor is the drive pulley and a pulley on a pump is the driven pulley. Example: The pinion gear in a differential is the drive gear and the ring is the driven gear.

Limited Slip Differential 3.55 gear ratio

don't know exactly what ur asking but the difference is the weight just like motor oil the heavy and thicker the harder for the parts to move but provides better protection on the gears so you need just the right weight usally ur car's manual will tell u what u need if not call ur local parts store there computers look almost any vechile, tractor or trailers these days.

dodge dealership told me about 120.00 for my 2002 dodge

In order to have good fuel economy and good performance, the best gear ratios for a jeep Cherokee with 33" tire size are:

3.91

4.11

4.27

Most common are "slipping" issues when a load is applied. Many of the Honda Odyssey transmissions were covered under a factory recall. Check your local dealer to see if this recall applies to your car. If it does, the transmission should be repaired, or replaced, free of charge.

Limited slip is a locking differential that distributes power evenly to both drive wheels.

Any Dextron/Mercon III automatic transmisison fluid will work in that manual transmission. The dealer recomends Mercon mulitpurpose automatic fluid. Macs Transmissions 281-394-4951 Macstransmissions@gmail.com

3.31:1 on automatics and 3.55:1 on manual transmission 2005-2008 mustang GT's In at least 2007, 3.31 gears were standard on a manual transmission but 3.55's were offered as an option.

The Rear Axle Code is on the door sticker...

BG - 3.31 - non-limited slip

CD - 3.55 - limited slip

CG - 3.31 - limited slip

Vehicles with front wheel drive have a straight rear axle meaning there is no gear housing in the rear axle. Vehicles that are rear wheel drive have a gear box in the middle of the rear axle to change the rotation of a drive shaft to turn the rear axle. If you look under a full size pick up truck rear axle you will see a large gear box (typically referred to as a pumpkin) in the middle area of the axle. That is the gear box differential.

it sounds like a humming or whinning noise, what year is the truck if its from like 01 or up those trucks have a lot of wheel bearinig problems that some one might misdiagnose as a differential noise or it could be chopped tires making the noise.

Manchester encoding transmits different waveforms to distinguish between 0 and 1. For example, 1 is represented by a high voltage for the first half of the bit, followed by a low voltage (or a negative voltage) in the last half. A 0 should be the exact opposite: low voltage in the first half and high voltage in the second half.

Wikipedia explains the principle of differential Manchester encoding better than I could:

A '1' bit is indicated by making the first half of the signal equal to the last half of the previous bit's signal i.e. no transition at the start of the bit-time. A '0' bit is indicated by making the first half of the signal opposite to the last half of the previous bit's signal i.e. a zero bit is indicated by a transition at the beginning of the bit-time. In the middle of the bit-time there is always a transition, whether from high to low, or low to high. A reversed scheme is possible, and no advantage is given by using either scheme.

80/90W In the rear end the same in the transmission as long as its a standard shift transmission and not a automatic

Serial number is on the left rear vertical frame member, visible from inside the LR wheel on a plate welded to the vertical member, plate is about 1" by 5" and 1/32" thick.

According to Haynes the 1995 has a hypoid, semi-floating type and some have the optional locking limited-slip axle. The identification and manufacturers codes are stamped on the right rear axle tube on the front side.
