Hey guys I need some help i thought this thumping from 4x4 and reg driving was the u joints so i did the front drive shaft and left and right front axle ones and spindle barrings but its still there there seems to be play in front axle connecting to front dif and thats all i can think of any advice??? Thank yall so much

 

in refrence to the " play in front axle connecting to front dif" are you referring to the axle tube where it connects to the front diff housing? Got any pics?

 

A better description of this "thump" would help your cause (a better description of the whole
Issue) and a better description of the part in question as already stated would help Your cause as well, help us help you lol.

 

and pictures pointing out the problem area with a good description would be ideal.

 

I further second the notion of the hypothesis' of my colleague's inference on your situation requiring further illumination of the problem at hand.

 

Sorry i was in a hurry typing it yesterday but its the pinion it has play and it jumps out of place when braking or 4x4 i dont have a pic im pretty sure its that sorry my cams not with me): is that hard to fix?

 

I'm not familiar with working on or diagnosing pinions... but from the sounds of it you have a bad bearing in there that needs to be replaced before further damage is engaged.

You might need a new pinion already as it is. Next week I'm flying home and I'm having new gears put in my axles. You can have mine for the cost of shipping if it turns out you need them.

I have a 98 XJ with the high pinion dana 30 and 3.55 gearing (ring and pinion). I can toss in my bearings and everything else if you want. They're all fine.

 

x2 It sounds like something in your front diff is messed up pretty bad. my advice when it comes to gear stuff is, unless you have experience with them, to leave that work to professionals. Gears need to be set up properly or you will just continue to have pretty bad problems. Its hard to tell what is actually causing the problem without opening up the diff and looking at it. Could be broken teeth, a bad pinion bearing, things like that. Either way it will have to be taken apart overhauled/ replaced and the gears will need to be re set up.

 

Thanks commando Whats your number and address?(: I hope it doesnt have to be sent to a shop):

 

I'm at zip-code 32134.

Until I get home I won't know what's going to be taking place. I'm hoping I can get my axles into a shop to be worked on while I'm home. I have a lot of stuff I need to do.

One of which is buy another XJ.
