Hello all, am pretty new to the forum, lot's of great info here. I have a 93 w250 extended cab and it has a driveline vibration between 40 and 50 km/hr regardless of which gear it is in. Just wondering if anyone has any insight into this.

New wheel bearings and brakes all the way around. New rear springs, new front driveshaft, new front u-joints,

Also the steering seems to really want to pull agressively when part way into a corner. The frame was cracked at steering box, repaired that and added frame brace off of a ramcharger. Put on borgeson shaft and tightened adjustment on steering box.

 

I would think driveshaft, or pinion angle if its a high frequency shake. If its a low frequency, I would start with tires.

Hard to say without knowing the details on your truck, eg lifted or not, stock tires or not...

 

Well, I just had a pretty bad Vibration, I installed a new rear driveshaft and it took care of the problem.. Your front driveshaft and front u-joints are out of the equation unless your hubs are locked... Not sure, but don't the extended cabs have a two piece rear shaft... If so, maybe check out the mid shift bearing if you have one..

 

yea we have 2 shafts with a bearing in the middle

 

Sounds like steering box might be too tight. There may also be an internal hydraulic issue with the steering gear. Welcome to 1gen. It always takes a while to get thru the probs that previous owners couldn't be botherd to fix but the result is well worth the effort!

 

I hear that every time I turn around there seems to be something else. I bought the truck for the 5.9 guess it comes with some baggage.

 

Any pics of the truck? What tranny is in it?

welcome to the forum .

 

No pics yet

Transmission is a getrag 5spd.

I have only had the truck for 3 months and so far I have replaced whl bearings, and brakes all 4 corners. Shocks, rear springs, frt u-joints and driveshaft, engine mounts, injection pump(industial engine) and injectors, steering shaft and installed ramcharger frame brace, and windshield. Also repaired 3 out of 8 spring hangers.

Still need to replace steering box, possibly rebuild king pins and rebearing NP205 and getrag. IT NEVER ENDS.

 

whats the deal with the ramcharger frame brace

 

It is a brace that bolts on the inside of the frame rail using the steering box mount holes and has a brace that bolts to the crossmember under the rad support.

Here is a link.

 

Here is a replacment too. Alot of 1stgens frames crack behind the power steering box so it helps reinforce it. http://www.dodgeconnection.com/catal...66/4541374.htm

 

get used to that, i bought my clunker for 3500, and have put in another 5g's in the last year. no body work, still looks horrible. My girl keeps telling me I could of bought a newer dodge, she just doesn't understand.

 

thats good to know, i have had the truck for a while but still doing things to it, one major thing is my tranny,getrags are hard to deal with.......atleast when no tranny shop wants to deal with them...thanks guys for the reply on the brace and links...
