Chrysler Caravan, Voyager Service Manual – What You Actually Get

If you’re tearing into a Chrysler Caravan, Voyager Service Manual driveline on a lift in San Antonio, you don’t need warm fuzzy marketing. You need the factory torque spec for that inner tripod joint seal boot retaining nut, and you need it in black and white. This is that black and white. 54 pages covering the differential and driveline section – front driveshafts, rear driveline module, half shafts, viscous coupler, and every seal along the way. I’ve seen techs ruin a $400 half shaft because they guessed the bolt pattern. Don’t be that guy. This doc came from the OEM, not some aftermarket reprint that changes numbers between editions.

Front Driveshafts – Identification and Service

Page 2 of the manual walks you through right vs left side driveshaft identification. The left side on automatic transaxle cars uses a solid short interconnecting shaft. Right side is longer. Both use a tuned rubber damper weight – the right side gets a single clamp style, the left uses double clamp. If you replace a shaft without matching that damper, you’ll chase vibration until you hang up your tools. The inner joint on both sides is a tripod joint; the outer is a Rzeppa (true constant velocity). The manual explicitly states that the inner tripod splines into the transaxle side gears and is retained by a snap ring. That snap ring is your first thing to check if you can’t get the shaft to seat. Don’t force it.

Noise Diagnosis – Five Symptoms You Can Address

The diagnosis and testing section covers five distinct noise/vibration patterns: noise or vibration in turns, clunking during acceleration, shudder or vibration during acceleration, and vibration at highway speeds. Each symptom points to a specific driveline component. For example, vibration in turns usually means a worn outer C/V joint. The manual walks you through a vehicle inspection before you start pulling parts. That step alone saves you from replacing a good half shaft. Most DIY guys skip the inspection and end up with a box of wrong parts. Read that section. It’s short – three pages – but it’ll keep you from buying parts twice.

Torque Specifications – Page 14

Every fastener in the front and rear driveline has a listed torque spec. Hub nut retention system: nut lock and cotter pin. Outer C/V joint stub shaft to wheel hub – use a torque wrench, not an impact gun. The torque spec for that hub nut is printed on page 14. The table lists thread size and torque value for all bolts, including the differential carrier end cover. If you overtorque the cover bolts, you’ll warp the housing and get a leak that takes all day to fix. I’ve done it. Use the spec.

Rear Driveline Module – Resealing and Vacuum Diagnosis

The back half of the manual covers the rear driveline module – propeller shaft, half shaft, viscous coupler, overrunning clutch, and torque tube. There’s a section on resealing the differential carrier end cover, overrunning clutch cover, and clutch case to rear carrier case. Each seal uses a specific RTV or gasket. The vacuum schematic shows solenoids energized and de-energized for the overrunning clutch vacuum motor. If your AWD Voyager won’t engage rear drive, check the vacuum lines before you pull the module. Page 45 in the manual has the schematic. Aftermarket diagrams often swap the vacuum ports. This one matches what Chrysler built.

Who Needs This Manual – DIY and Professional

This 54-page document is aimed at anyone who’s replacing a front driveshaft, resealing a rear carrier, or chasing a driveline vibration. Home garage enthusiasts will appreciate the step-by-step removal and installation sections for front driveshafts (page 3–8). Professionals get the special tool list – you’ll see things like C/V joint remover and installer kits. If you’re a junior tech who’s never reconditioned a half shaft, the disassembly and assembly section for the inner tripod joint seal boot and outer C/V joint sealing boot is worth reading twice. Each boot removal and installation procedure includes cautions about bearing shield retention. Overlook a bearing shield, and you’ll contaminate the wheel bearing within 1,000 miles.

Why Factory OEM – Not Aftermarket Copy

AutoRepairManuals pulls directly from the original Chrysler print. That means the torque spec for the front overrunning clutch seal is the same spec Chrysler used when the car left the factory. Aftermarket manuals rewrite sentences to avoid copyright violation, and they frequently change torque values by a couple ft-lbs. That difference is enough to strip an M8 bolt into an aluminum case. I’ve seen it. This manual is a scan of the official Chrysler service manual – no editorial changes. It includes the note on page 1 about the bearing shield design that replaced the old rubber lip seal. That detail saves you from trying to buy a part that doesn’t exist for your model year.

FAQ

Does this manual cover the manual transmission version of the Caravan?

Yes. The front driveshaft section specifically mentions vehicles equipped with either automatic or manual transmission. It covers the unequal-length driveshaft system used on both. For clutch or transmission internal work, you’d need the transmission volume – this is the driveline section only.

What about the rear driveline on a front-wheel-drive Voyager?

No rear section on FWD models. Only AWD.

Before you start pulling the rear driveline module, double-check your vehicle options. The Chrysler VIN Plate Decoding Information will tell you if your van was built with AWD. For transmission-specific procedures, refer to the Manual Transmission section of the full service set. The Chrysler VIN Plate Decoding Information Manual gives you the axle code breakdown. If you’re ordering half shafts, the Chrysler Caravan Town & Country VIN Decoding Information helps narrow down the correct part. And yes, the correct torque for the driveshaft-to-transaxle bolts is in this manual – you don’t need to guess.

One more thing: the Manual Transmission cars use a different left-side interconnecting shaft than the automatics. The manual notes it. If you skip that detail, you’ll be reinstalling the wrong shaft. Access the Factory Manual and print the torque spec page. Tape it to your toolbox. You’ll thank me when the cotter pin slides in first try.
