05 cab & chasis-likes to hop

[Brassfield]

Got an 05 2.5 truck, cab and chassis. I have all the normal stuff done, hitch hooking point moved up, t bars lowered, rear suspension stops, center link brace. For some reason though I keep lifting the left front and start hoping. We did notice the that only the left front tire is spinning so we are going to linclon lock the front diff, but I really don't think an open front end will cause the hop. Any thoughts??

And its not the one in my sig pic, new one is to ugly for a pic:roflmao:

 

[clrussell]

Driver error possibly? Need to work on your clutch skills??


He didn't mention but it if a zf-6 truck.

Take the sway bars off the front and rear of the truck. Post a video of it hooking

 

[Brassfield]

Ok can try that, hadn't heard of that yet. I don't have a video with my own phone. I'll see if I can get a hold of one

What tires and psi? Any traction bars in the back?

 

[Brassfield]

Yes traction bars. 285s on duals on the rear-50psi. had 305/55 20 on front, tried 50psi then tried 20 psi-same results. Going to put some 285s on 16s up front for this weekend

 

[Brassfield]

duals are toyo at2. Atzs up front, gonna try some bfg at kos up front hopefully.
tried loading and pre loading bars already to

Best thing to do is get a very good video of it making a hook and post it. Usually the crowd here is very very good at getting stuff figured out with a pulling truck.

Are the bump stops solid in the rear or do have a inch gap or so before you hook to the sled?

 

[Brassfield]

1/2" gap roughly. CLrussel has a vid I think

 

[clrussell]

I have a vid, if someone with an phone would like me to send it to em let me know. I don't know how to upload to you tube

A lot of "traction bars" are under built. Duals tend to bring out the weakness in these bars.

try running a little more gap between the stops. if I don't hang weight, I cant run solid rear, or else my front end hops

X2. Try one inch. And make sure u measure exact

Figured that out on the first set of bars for this truck. This set should not have any problems

So do you have 2 sets of stops or just pull em out if you don't hang weight?

Will measure and trim to exact 1"

His last pull truck was a crew cab long bed dually. I believe the stops were like 1/4" from touching with nothing in the bed. B/c if there was anything in the bed you had to jack the hitch up a little to get the stops in.

Also rear tire pressure can make bad things happen

Suggestion on where to start on air pressure? I believe his last truck with 285s he ran about 45 in the rears and front was like 30?

Low rear pressure cost me driveshafts and ring and pinion
