Why is My Car Vibrating? Understanding Tailshaft Issues

tailshaft repairs near me

Ever hit the open road, cruising along, and suddenly your car starts doing the jitterbug?

Definitely not a great feeling.

Car vibrations can be a real pain, and often, the culprit hiding beneath your vehicle is a dodgy tailshaft. Let’s take a closer look as to why your car might be vibrating and how tailshaft issues play a part.

Get to Know the Culprit

First things first, what exactly is a tailshaft? In simple terms, it’s that long, spinning rod under your car that connects the gearbox to the differential.

Think of it as the backbone of your car’s drivetrain, transmitting power to the wheels and getting you moving. When this crucial component starts acting up, you’ll definitely feel it.

Spotting the Signs of Tailshaft Trouble

Vibrations are a telltale sign of tailshaft issues, but they’re not the only one. You might also notice clunking or banging noises, especially when you accelerate or change gears. If things get really bad, you might even experience a complete loss of drive – definitely not something you want happening on the highway!

Keep an ear out for any unusual noises and pay attention to how your car feels when you’re driving. If something seems off, it’s best to get it checked out sooner rather than later.

Common Causes of Tailshaft Vibrations

So, what causes these vibrations? Well, there are a few usual suspects.

One of the most common culprits is a worn-out centre bearing. This component sits in the middle of the tailshaft and helps keep everything balanced. Over time, it can wear down, causing vibrations, especially at higher speeds.

Another issue could be universal joint (known as U-joints) wear or damage. These joints allow the tailshaft to flex and move, and if they’re worn, you’ll feel those vibrations creeping in.

And let’s not forget about a tailshaft imbalance. If the tailshaft isn’t properly balanced, it can wobble and vibrate like crazy.

Don’t Ignore the Shakes and Shimmies

Ignoring tailshaft problems can lead to some serious headaches down the road. Not only can it make for an uncomfortable ride, but it can also cause further damage to your vehicle and even lead to costly repairs.

Think of it like this: if you ignore a toothache, it’s not going to magically fix itself, right? It’s the same with your car. Addressing tailshaft issues early on can save you a lot of trouble and money in the long run.

Get Your Ride Back on Track

If you suspect your car’s vibrations are due to a tailshaft problem, it’s time to call in the experts.

A qualified mechanic can diagnose the issue and recommend the best course of action, whether it’s a simple repair or a complete tailshaft replacement. Our team at GJ Drivelines has the expertise and the equipment to solve your problems.

T-400-4L80E – 32 Spline 1 7/8″ Seal Diameter

Note: Transmission slip yokes are manufactured with various U-Joint Series. It is important to match Horsepower and Torque requirements to U-Joint Series. For aftermarket transmission applications usually a spline count and seal diameter will identify slip yoke required.

Identify Rear U-Joint

If Pinion Yoke has Placement tabs that retain the U-Joint, measure inside tabs. See Diagram D.

diagram-e

If Pinion Yoke does not have Placement Tabs that retain U-Joint, measure from flat of yoke inside to inside. See Diagram E.

If 4 bolt Flange is used on pinion, measure Pilot Diameter and center to center diagonally bolt hole to bolt hole. See Diagram L.

Universal Joint Size. There are hundreds of U-Joint sizes or “Series” to accomodate many different applications of power and desired longevity for your automotive, 4×4 truck or auto racing requirements, these 4 series of joints cover most needs.

1310 Spicer Series: 1 1/16″ Cup Diameter (Dim C – Diagram A) 3 7/32″ length (Dim B – Diagram A) Certain Ford applications have 2 cups 1 1/8 Diameter. Appropriate horse power range is up to 500 in circle track or road racing, small tire drag racing and 4×4. Also available: Performance Dynamic Cryo Joint.

1330 Spicer Series: 1 1/16″ Cup Diameter (Dim C – Diagram A) 3 5/8″ length (Dim B – Diagram A) Certain Ford applications have 2 cups 1 1/8 Diameter. Slightly stronger than 1310, Used in 5.0 Mustangs. Also available: Performance Dynamic Cryo Joint.

3R Saginaw Series: 1 1/8″ Cup Diameter (Dim C – Diagram A) Retained with internal clip 2 5/8″ (Dim B – Diagram A). Most common GM joint. Horse power range up to 700 in road racing and circle track. Solid drag racing U-Joint can accomodate most sportsman classes. Also available: Performance Dynamic Cryo Joint.

1350 Spicer Series: Manufactured with OEM tolerances and treated with our Cryogenic Process to yeild the strongest U-Joint available. For drag racing applications a solid non-lube design U-Joint is recommended because of the tremendous initial shock load, or short duration of high torque the joint must be able to withstand.
