questions on a lot of issues...

[enys5000]

Hello , I'm new and own a 98 4d 4wd lt . It has about 150000 on it . I've had a lot of problems and replaced parts including a tranny ---which it has never been the same. I have some weird noises going on noone can figure out. to me it sounds like bearings ---hear it good when decelarating sounds like a train slowing down. I also hear this humming sometimes ---this truck used to be so quiet no I hear everything....Does anybody here have any ideas on these things. I am getting ready to use it to tow a 16 ft cargo trailer with my tools ---not too much weight but some know it alls say my rear end wont be able to take it ---the truck came with a hitch but no wiring so I'm not sure if its a heavy duty package ---how do you tell. If not will it be able to tow this trailer --It is a united 7 ft wide x 16 --will have a 750 # machine up close to the front and the rest of my tools --probablly under 1000 # everywhere else. any advice is appreciated.

i would get the truck on a hoist and get under it when its doin it and that way you can pinpoint where the noise is coming from ,could be transfercase,u joints,bad tranny

i would check out the slip yoke, u joints and the rear end.

8.5 rears are common to pinion bearing failures. I would check out the rear axle really well.
