Advice on another newbie error.
We went to Fraser Island in July. Had a great time driving all over the Island which was a first for me in sand.
When we came off the Island there was a bit of a shudder from the rear of the wagon, a 2002 3ltr Patrol wagon, 230000 ks on the clock at the time.
Went to the car wash and gave it a good clean both on top and underneath to remove any sand and salt water residue.
Still had the shudder in the rear, mainly when turning tightly.
Drove home to Albury and contacted the dealer about the shudder the next day.
They replied that it would be sand built up on part of the drivetrain and that it would vibrate loose and disappear over time.
It did disappear almost completely and I almost thought it was right.
I towed our boat to Bermagui with 2 mates, going up Talbingo under heavy load and again around corners, the shudder returned.
One of my mates who ran his own mechanic shop for 30 years said , whats wrong with the diff.
Too cut the story a bit shorter, I booked the Patrol into the dealer when I got back from fishing, they discovered the rear diff breather had come off, drained the diff oil which was milky in color and said all could be okay.
At the next service I got the diff oil changed again but I still have the shudder under load, towing and tight corners.
1/ Have I done irreparable damage to the LSD in the rear?
2/ If so, do I a/ get it rebuilt, b/ buy a new one, c/ replace it with a locker, either electric or air?
I do not do any extreme 4 wheel driving, it was purchased to tow, having said that it will eventually be a mild touring vehicle towing a van of some sorts.
Guessing I would of done around 2.5 to 3 thousand kilometers with the shudder.
I had the truck serviced before we went, I did not do any daily checks at Fraser, I didnt trust my instincts when the shudder was noted, now I get to pay.
thanks
Doug.
