I have been getting some vibration, when accelerating hard at speed, since the truck was lowered (3/5). I'm guessing that the driveshaft angle is off and the axle needs to be shimmed. Any recommendations on where I should take it? It's a 2010 Silverado ecsb if that matters and I'm in north Dallas.

 

what did you lower it with? flip or s/h? I can help you craig. pm me.

 

Actually, it's been lowered for almost a year and I keep putting this off. It is a flip kit. I will PM you.

 

is it a 2 piece driveshaft? if so did you do the carrier relocator?

 

I hate to admit that I don't know the answer to that question. I would assume it's 2 piece. I had a shop lower it but their specialty is more cars (IRS) than trucks. I don't remember anything about the carrier being relocated.

 

Ya know, now that I think about it, it might actually be getting down onto the bumpstops at these times. Could that be it? It will hit them on a hard bump. I did not get a c-notch but I probably should have (helper bags are on the list BTW).

 

It is a 1 piece driveshaft. Looks like the pinion is pointing at the trans to me but I'm not getting a good look with it on the ground.
