Check your driveline angles first. This is the most probable cause. Here's a link to some info explaining what you're looking for

thanks, im just going to call the shop tomorrow and see when i could drop it back off , and see if they can figure it out, but shims should fix the problem????

IF your angles are out of spec, then yes, shims should fix it. But the shop will need to verify that is the actual problem first.

Bell tech drop spindles now in. I'm also using drop struts at the 2'' setting. 

 

Here's some pics of the spindles since there's not much about them online 

 

 

Compared to the stock spindle

 

 

And my truck:

Hey guys. New here to the forums. This may have been discussed... I have looked through some pages and honestly cant get past looking at the pictures of all the awesome trucks builds! I have a 2014 Sierra 1500 4WD Crew Cab. I want to level the truck by lowering the rear. I don't haul anything heavy or tow. However, I have to remember Mom & Dad need to get in sometimes. I was told removing the stock blocks under the leaf springs would level it with the front. Is this true? Or, is the better option to buy the lowering shackles? Thanks in advance!

I believe the stock blocks are 1.25". So in theory only removing blocks should get you 1". Adding 2" lowering shackles and removing stock block or moving block from under leaf spring to on top of leaf spring will get you 3 inches which should level the truck.


This truck has total of 3" drop in the rear.

Thanks for the info. Is that 4wd? What option did you use to lower?

Finally installed my shackles this weekend. Not completely level... I'm debating on dropping it more.

 

Also trying to get mounting hardware for my rear fender liners. No way I'm giving GM they much money for that stuff

 

Also what's your driveline angles looking like when you pull the blocks on the axle? Any degree wedges needed?

I had to get shims after shackles and removing the blocks because of vibration.  I also ended up needing to get an adjustable carrier bearing from belltech I believe.  Although my truck is a crew cab with a 6.5' bed so I have a two piece driveshaft.  I think any other configuration is just a one piece driveshaft so you probably wont need a carrier bearing.  Vibration also varies from truck to truck, yours may be fine.  If its not and you insist on ordering the shims before doing the work, buy 2* and 4* shims and one of those will likely fix the vibration.

I haven't had any issues since pulling the blocks. I'll probably still get under there and measure it since I'll eventually be pulling a small camper

Needing some advice on lowering my pickup. This will be my first time lowering a vehicle. From the research I've done I think I want to do 3/5. I've been looking at different kits and found the Mcgaughys #34170 Adjustable Drop Kit. Looks pretty decent, but I have no idea. I like that if I would want to go lower I could. Any input would be great. This is the link that I found for the kit.https://reklez.com/collections/2007-2017-gm-trucks-drop-kits/products/gmc-sierra-1500-2014-2016-3-5-4-6-drop-kit

Any info or input for a newbie would be awesome. Thanks
