Five problems related to differential unit have been reported for the 1998 Dodge RAM. The most recently reported issues are listed below.
Very loud noise was coming from rear differential. Contacted dealer. Please provide further information.
Locking pinion nut broke, resulting in shaft to fall which caused damage to the pinion gears and spindles. Several mechanics stated that a locking pinion nut should never unlock or break. Thus it's defect caused 1,100 worth of damage and could have definitely resulted in injury.
Pinion seal replaced three times ,ring and pinion replaced at 32000 miles,pinion nut allways reused never a new pinion nut . Fourth time pinion nut comes off at 108000 miles at 65 miles an hour . Please advise. Dealer says not responsible .
Ring & pinion gear failed. Dodge has more than 1200 on back order and cannot get the part. My part has been on order for 5 weeks. Local dealer confirmed that Dodge has sent them a notification to try to reset the ring & pinion gear as a fix rather than replace the part. Dodge customer service hotline will not confirm that they are having problems with this part.
Rear differential broke. Vehicle has been inspected. Dealer and manufacturer will be notified.
