According to Au7o's research across NHTSA recalls, manufacturer TSBs, and owner forum reports, the 1995 Jeep Wrangler has 5 documented known issues, with 2 rated critical. The most serious are Body Tub, Floor Pan & Body-Mount Rust (Torque Box Corrosion) ($400-$3,500 repair) and Dana 35 Rear Axle Shaft C-Clip Failure ("Grenade") ($300-$2,200 repair). Across all issues with published estimates, repair costs range from $20 to $3,500. DIY maintenance guides at au7o.io.
On the 1994-2006 Jeep Wrangler, the Dana 35 rear axle fitted to most non-Rubicon YJ/TJ Wranglers uses a C-clip design: each semi-float axle shaft is retained inside the housing only by a C-clip seated in the differential. If a shaft snaps — common with 33-inch-plus tires, a locker, or aggressive trail use — the wheel and outer shaft can slide completely out of the housing ("grenade"), damaging brakes and potentially separating the wheel while driving. A top-searched off-road reliability weak point.
For stock use, keep tire size sane and inspect shafts/seals. For lifted or wheeled rigs, upgrade to chromoly/one-piece shafts, install a C-clip eliminator kit, or swap to a Dana 44 / Ford 8.8 rear axle. Crown/Omix replacement Dana 35 C-clips and shafts (e.g. Crown 5012826AA shaft) are available for repair; a broken shaft requires pulling the diff cover to retrieve the clip and inner stub.

On the 1994-2006 Jeep Wrangler, the NP231 (Command-Trac) transfer case in YJ/TJ Wranglers uses a slip-yoke rear output. The rear output shaft seal is a chronic leak point — the exposed slip yoke picks up grit and rust that scores the seal, and a worn tail-housing bushing lets the yoke move and tear the seal. Result is ATF weeping from the back of the t-case, a very common older-Jeep drivetrain search.
Replace the rear output shaft seal (National/SKF 18662 or equivalent) after cleaning/inspecting the yoke and tail bushing; tape over the retainer-clip groove during install so the seal lip glides past it. If the tail bushing is worn or a lift causes driveline vibration, install a Slip-Yoke Eliminator (SYE) kit with a fixed yoke and a CV driveshaft (Rugged Ridge/Omix 18676.62 housing seal). A basic seal fix is inexpensive.

On the 1994-2006 Jeep Wrangler, distinct from frame corrosion, the steel body tub rusts from the inside out on older Wranglers, especially in salt regions. The spot-welded body-mount channels ('torque boxes') under the floor, the floor-pan seams, and the rocker areas trap moisture and rot around the three body mounts on each side — a critical structural/search topic for buyers of high-mileage TJ/YJ examples.
Inspect all body mounts and floor seams; light surface rust can be wire-wheeled, treated with a rust converter, and protected with Fluid Film. Rotted torque boxes/floor pans require cut-out and weld-in replacement panels (e.g. NIXFACE full tub body-mount repair kit, C2C Fabrication weld-in floor and torque-box panels) plus new body-mount bushings. Address before any lift or armor install.

On the 1994-2006 Jeep Wrangler 4.0L I6 (PowerTech), a leaking rear main seal is nearly universal on high-mileage 4.0 Wranglers — the two-piece crankshaft seal hardens and weeps oil at the back of the block, dripping onto the bellhousing and often collecting at the transmission. It is one of the most-searched 4.0 oil leaks and is frequently confused with an oil-filter-adapter or oil-pan-gasket leak.
Common Symptoms
Oil drip at back of engine / bellhousing
Oil spots under the transmission bell area
Low oil level between changes
Oily film on skid plate
How to Fix
Because the 4.0 uses a two-piece rope/lip seal, the rear main can be replaced without pulling the transmission — drop the exhaust, oil pan, and main bearing support/cap to swap the upper and lower halves (Fel-Pro BS40183). Refresh the oil pan gasket (Fel-Pro OS34308R) at the same time. Correct RTV at the seal parting lines is critical to avoid a repeat leak.

On the 1994-2006 Jeep Wrangler 4.0L I6 (PowerTech), one of the most common 4.0 oil leaks: the valve cover gasket hardens and seeps, typically worst at the rear of the head, leaving oil and grime down the back of the block and sometimes dripping onto the exhaust (burning-oil smell). Frequently mistaken for a more serious rear main or head-gasket leak.
Common Symptoms
Oil seepage down the back/side of the engine
Burning-oil smell after driving
Oil pooling in spark-plug tube area
Grime buildup on the head
How to Fix
Replace the valve cover gasket — Fel-Pro VS50458R (or VS50522T, which has integrated bolt eyelets). Reuse the metal spacer inserts, replace the rubber grommets, clean both mating surfaces, and do NOT over-torque the bolts. Later steel-cover TJ/LJ 4.0s use the eyelet-style gasket. A cheap DIY fix.

POWER TRAIN:CLUTCH ASSEMBLY:PEDAL/HAND LEVER(MOTORCYCLE)
Chrysler (FCA US LLC) is recalling certain model year 2006 Dodge Viper and Jeep Wrangler and Liberty vehicles manufactured July 1, 2005, to July 31, 2006. In the affected vehicles, the springs within the clutch pedal position switch that prevents the vehicle from starting unless the clutch pedal is pushed down may break. As a result, the vehicle may not be started when the clutch pedal is pushed down or the engine may crank and start without the clutch pedal being pushed down causing the vehicle to unexpectedly lurch.
