Transmission/Rear End Vibration at take off

Rocket67 · 09-06-2005, 01:47 PM

Ok, this weekend I hauled the largest load thus far on my titan.

ATV = 800lbs
ATV = 800lbs
ATV = 650lbs
ATV = 500lbs
Trailer = 1800lbs
Equipment = 200lbs

So, just under 5000lbs or so plus passengers.

The problem:

Every time I took off I felt a vibration/judder. It's like the brake problem except at take off and it was much stronger. Once the trailer/truck got moving a little bit it would go away. I do not have this problem with an empty trailer (1800lbs) or just the truck.

I have a 2004 Titan SE with about 11K miles on it.

Anyone have this problem? I searched the posts and found the transmission bolt issue and the rear diff problem but no one really had the same symptoms.

I haven't heard of anyone else having this problem, but could it be torque converter shudder/chatter or whatever you want to call it?

I didn't have any of these symptoms this weekend pulling my 8000-lb travel trailer.

Maybe the trailer itself has an alignment problem (or maybe the trailer has an alignment problem when loaded down?)

Had the trailer a while and hauled a lot of loads on it...never been a problem with my brothers Explorer either. Once the load gets moving it stops.

maybe it's the trailer with all that weight on it. when i towed my buddies samuari, i had vibration on take off, then it'd go away, that's because of the tires, procomp Xterrains. that sami is probably 1200lbs. i also tow our boat which is about 2600lbs and it's clean as a whistle. it's probably your trailer. hook the trailer up to another truck and see what happens. good luck!

Had the same load on the same trailer with a different truck......no problem. Plus...it doesn't do it until there is a load on the truck...for example...if I don't give it much gas it doesn't do it....or if I am facing down hill...the drivetrain has to have a strain before this happens.

I will double check with another truck but this trailer is about 4 months old and hasn't had this problem with another truck...I am thinking it's something in the Titan.

have you taken it to the dealer yet? does it do it every time?
have you chagned your diff fluid to the synthic? i noticed you have an 04.

i have had the same problem for a few months and just found the problem. It was a broken rubber transmission mount on the crossmember. makes poping on hard takeoffs or under heavy load.

This is more of a judder/vibration but no noise. I haven't taken it to the dealer yet but plan on it soon. I just want to make sure that the problem is reproduced each time the circumstances are the same.

I haven't changed out the fluid in the diff yet..what weight should I use? IO have some Royal Purple 75wt that I can swap out this weekend.

That is what mine did when the rear end went bad, take it it, I bet they put in a new rear.
