hi everyone new to the site i own a 1990 tracker 5 speed 4by 4 the tranny is grinding and poping alot the only to stop it is to lock into 4 h i just replaced the t case today and the same thing im outta ideas

[jtgh]

please explain better (sorry)

does your car grind gears , going from neutral, in driveway, engine running, then shifting to any gear ,before letting clutch out.?

what is poping?

[rayman]

sorry what it does when i take off i get to about 3rd or 4th gear and it starts grinding real loud and ill start slowin down and itll pop real loud i dont know what is poping i can put it in 4h and drive and it stops i changed the t case today and it does the same

[jtgh]

so let me see.
it shift perfect then.
i presume you checked fluid levels ,straight away right/
ok
both 2h , 4h a 4L it does this?

bad UJoints? did you grab them and gorrilla them to see if they rattle or are loose?

cheers.

i did fill everything up to proper levels it shifts good and the t case is quiet its like its tryin to kick in to 4wheel on its own thats why i changed the case but it still does i checked all u joints and tranny mounts

[relicduke]

Does it make this grinding noise in 2wd or just 4x?Didja check the mount on the front diff? I had this problem{at least the same noises}a bit ago,the mount on the front diff had quit and the yolk was rubbing on the bell.
good luck

Does It do it going around a curve ?

[rayman]

it does it in a curve to it starts out in 2 wheel drive and i put it in 4 wheel and it stops

[jtgh]

4wd it stops (2wd noise ) you need to better explain that noise.
and all gears and reverse !

remove the locking hubs and repeat the tests. (top fail on this site)

the locking hubs do NOT hold the wheels on.

it is common for dirty rusted hubs (4wd locking of any kind) to get stuck half in and half out,and make big problems.

its a 7.5K mile service point. Inspect, if dirty clean, then re-grease them lightly with marine grease.
swap out of front hub bearings

and better

looks like he's down. (above) too bad, best photos ever !!!
