Ok, guys. I have serious problems. I have a 93 xlt bronco. It is not running right at all. I am not mechanically inclined, so I really don't know what is the problem. I can't really drive it for long until it makes all kinds of noises. I am not sure if it is the tranny or the rear end or the ujoints. I purchased it back in sept of last year. I drove it through the winter and through some mud and stuff, but now it is broke. I have looked in every forum to try to diagnose it, but everytime I see something that might be the problem, there is something else that pops up and looks like the problem. I am in the navy and don't really have alot of money to fix everything, but would really like to get my bronco on the road again. I don't really won't to take it to a shop until I absolutely have to. I would really like to do the work myself so that I can learn how to fix things. If there is anyone around or near KENOSHA, maybe someone who knows what the heck is going on could take a look and teach me some things. I would be more than willing to throw in some beer or something. I am desperate to get my truck on the road and go topless. Any help would be greatly appreciated.

 

Can you explain to us what is happening- when-what sounds. Im in jefferson, wish I was closer wouldn't mind helping but that is about an hour and change from here. Maybe we can help you over the net. Another good thing is to get a haynes or chiltons manual. Will break things down step by step.

 

Well, let's see. Where do I begin? Ok, the first noise is when I start it up. It comes from underneath. I think it comes from the transfer case. Almost sounds like a rattling or maybe even like the noise you get when you shake a can of spraypaint. I am not sure. I have a haynes, but It's almost as if you need to be a complete mechanic with the schematics that it has. The second noise is when I put it into reverse. CLUNK! and then it kicks in reverse. I have driven it like that, and it has severe vibration until it warms up. Once it warms up, it starts to really bog down. I also think that I need to replace the fuel filter or pump. That is the least of my worries right now. It really makes a loud clunking noise when I try to drive it. I looked at the u-joints and I think I need to replace them. I am not sure if I have to change out the rear-end or what. I hope that it is not the tranny. I don't think itis, but I really don't know. It actually subsides the faster you go. I don't know. It also dies when I am at a stoplight after it is warmed up. Well, there you go! That is about all that I can describe.

 

drew,

I'd start with the joints and rear end and work forward. Pull the drive shaft off and replace the u-joints. They're pretty cheap and can be replaced with a vice and some sockets. Might as well do the front shaft while you're at it.

While the shaft is off, put the rear axle up on jack stands and spin the wheels. It should spin smooth. If not, you'll have to open up the dif and take a look. If it feels good, drain and refill the lube anyways. I'm guessing you have an 8.8 rear and it should have a rear dif cover. Put a drain pan under the dif and remove the cover bolts. Carefullt pry the cover off and drain all the fluid out. You want to look at all the gears in there and see if any are chipped or broken. Look for metal shavings in the bottom of the dif and in the drain pan. Also check for play in the yoke coming out the front of the dif.

If everything looks good, put a new gasket on (or just use RTV), button it all back up and put in new fluid. If you have a Trac-Loc (posi) rear end, make sure you add the friction modifier.

Before you put the drive shaft back on, check the t-case. Put the tranny in N and spin the rear output yoke. Check for grinding/clunking and play in the yokes. I don't knwo much about the t-case in these newer models so I can't be much more help.

This should be a good start, though. U-joints are a very common problem and relatively simple to replace.

BTW, check the front axle u-joints out at the wheels. Those go bad too.

Let us know what you find.

ok, just replaced the u joints. Man, they were trashed. However, i still have problems after I drive for a short time and bronco warms up. I can't go in reverse. Is it the rear diff? I hope it is not the tranny. It drives fine in drive, just not reverse. I feel that I may be taking the diff off soon and seeing my gears all jacked up. I don't know. If there is anything else to check, maybe someone can help me out. THanks!

 

So, does anyone know a good place that will rebuild my tranny (E40D) for cheap? SE wisconsin or Chicago. Thanks!

 

Well, just got my truck back from the shop and $2000 later it runs great. They had to do a complete rebuild. Oh well, at least now I have the peace of mind that I won't break down and I can hit the mud and snow when it comes! Thanks to everyone who tried to help. I love this site!

 

Glad to hear it all worked out! 2k is a lot of coin, but I think these things are worth it.

Did you have the rear end looked at too?

Kevin K.

 

No, not yet. I have to save some more money for that. It really drives awesome though. I love it!
