'98 cherokee frnt differention popping noise
I need any help possible on this one.
This is what I have;
My daily driver is a 1998 Jeep Cherokee 4.0L 4wd 4speed automatic 166,000 miles VIN:1J4FJ68S4WL173795
This is what it is doing;
Making a popping noise most offen when I turn left or right after initially starting to move. I can get the jeep to make the noise by turning the wheel to the left and moving slowly fwd. I can get it to make the popping noise again by putting it in reverse and keeping the wheels turned to the left move slowly backward.
The vehicle is not in 4wd when it makes this popping noise
When I do put the vehicle in 4wd it runs fine as long as I don't go around any sharp turns. There are 2 4wd settings; 4H, and 4L. There is another setting, 2H which is what I run in all the time.I can do 60mph in heavy rain with it in 4H with no problem. 4L is for going up hills at low speed which I don't do.
I just put new synthetic gear oil (140W grey bottle by SuperTech I believe)in both front and rear differentials. When I pulled the front cover off of the differential, I did not see anything obvious but then I wasn't looking for anything specific.
Two people have said the noise seems to be coming from the front differential. The front axles have universal joints not CVJ. They looked OK.
My questions are;
How can the noise be coming from the front differential if I don't have it in 4WD?
If I take the front differential cover back off to inspect, what should I be looking for that would make this noise?
What else should I check for?
You guys have saved me lots of $$$ already from previous posts.
As always, any and all responses are greatly appreciated
