Truck hop..jiggles my man boobs!!

[silly34]

Ok so after driving the truck now for about 2 weeks and now driving to Arkansas from Georgia (still in AR at hotel room :-X18 ). I've come to realize that my hopes of the truck hop is being caused by the road is not true. I've experimented several times and have found that the truck starts to hop (jiggles my man boobs pretty good) starting at 42mph and worsens at 45 but then starts to fade when it gets to 50mph (normal driving). When I accelerate heavy through 40-50mph no hop. When decelerating there is hop, I placed the tranny in neutral and it is still there.

So what now??


Thanks!

I guess you need a bra?? Just Kidding!!! What all has been done to your truck? Stock or lifted? Chipped or stock?? Give us some info so we can try to help.

Completely stock, tires looks new but not a major name brand. Had the alignment checked and it was not out. Just finished greasing the slip-yoke on the drive shaft but the hop was happening before I did that. The tires don't feel out of balance rides good 65+ on the freeway.

nother check point while youre under the truck is the carrier bearing. See if it has play in it, or appears to be damaged or anything. Just some ideas.

What year is the truck and how many miles?

[silly34]

I was thinking carrier bearing (heard it mentioned on another thread) but I don't know what it does or what to look for. It probably should be replaced (truck has 158K miles), something I can do?

Do you have Pro-Comp Tires by any chance?

[silly34]

No pro-comp tires

Just curious. Mine does the hoppi-d-hop too and I believe it might be my tires as it didn't do it before and now it does. Good luck finding the cause.
