i just pick up a 88 ram 50 4x4 and when im driving and go to put it in 5th gear the truck shakes and makes a knocking sound but it doesnt do it in any other gear a guy told me it was the throw out bearing any input would help thank you

Check the gear oil level in the tranny - it may be low. Otherwise, it could be a bad bearing on the shaft for 5th gear, bad syncro or debris in the teeth of the gear. For it to be the throwout bearing, all gears would do it. Actually, drop the pan on the tranny and see what you find.

Ill try it out and update on what I find thanks for the info

[dsam1989]

will now it wont go into any gear but 4th and the clutch rattleswhen i let my foot off of it

Main input shaft bearing failure - my 85 did the same thing just before the bearings exploded in the tranny. Stop driving it and drop the pan to see if it ruined the case.

thanks for the info

this is what im looking at 4718

[pennyman1]

is that gear oil or metal on the teeth - its hard to tell. Was there metal shavings on the pan or in the oil?

[dsam1989]

thats oil and no there wasnt shavings

It could be the pilot bearing in the end of the crank is toast. It will cause all kinds of problems if it's bad. Then you can destroy the input shaft bearings. Sorry to say it, but I would pull the trans and replace the clutch and inspect the shaft and make sure the trany bearings are not bad. The input shaft should move around some but not a lot.

[pennyman1]

I second that - once you get the tranny out grab the input shaft and see how much play there is - I'm betting alot, aka dough mixer.

gotcha thanks a lot guys for the info you really helped me out i going start on it again tomorrow
