Hello from France
I am French and I apologize for my bad English. The school is far away and I did not stay long. So thank you google for translation.
I am 52 years old, I have a 2002 Grand Cherokee (WJ), bought used in 2003.
This is a "Limited" model with a Mercedes diesel (5-cylinder, 2.7-liter, 163 hp) 5-speed automatic transmission (QuadraTrack).
It has 136000 km and the front differential make noise (whine).
Otherwise no major problems, only small electrical problems (Heated seats, switches, cruise control that does not remain in memory ....).
I come to you to read your advice ...
Thank you for welcoming me among you.
PS: You can correct my English, I will not be offended.
