Shims?

Hey fellas, so I recently put in Dakar leaf packs, and ome 886s. I now have what I can only figure is a driveline shake. I dont feel it in the steering wheel, and it's only in the 60-70 mph range I think. Ive seen somewhere that putting a shim in the rear could potentially help. So my question is should i shim it, and what shim should I get? How tall I mean. Any recommendations on where to get the shim? I'm Canadian as well, if anyone from the north knows where to get the proper shim.

 

The first thing you have to do is figure out where the vibe is coming from. It could be from the needle bearing because of the height of the 886's. Put it into 4 wheel drive and see if the vibe goes away. If it goes away, replace the driver side needle bearing with a ecgs bushing. Might be a good idea to do anyway if you haven't. If the vibe is coming from the rear, you first have to measure the angles of you driveline. There are a number of thread on how to get the driveline angles. Once you have that, those threads will tell you what degree shim to get. It is all relative and EVERY tacoma is different. You can get the shims a headstrong offroad or wheelers offroad. Welcome to the sherlock Holmes club....vibe investigation....

 

I should have noted that I do have the ecgs bearing already. Needle bearing failed last year.
Thanks for the info on the driveline angles, I'll definitely have to research that tomorrow!

 

Still can’t figure out for the life of me why the leaf spring manufactures don’t put a degreed shim on from the factory on any spring that has 2 or more inches of lift.

 

Rule of thumb is 1 degree of shim angle for each inch of lift. (1 inch =~25mm)

 

Yeah that would be awesome wouldn't it

Thanks mate

 

Do you guys think I could get away with just new shims and not the bolt that comes with the toytec kit? I can get procomp shims for 20 bucks canadian delivered, where as the toytec kit is 32 bucks usd before shipping to Canada. Going with a 3 degree shim

 

I guess you're talking about the leaf pack pin bolt. Best advice is to crawl under the truck. Measure how much surplus pin is showing above the nut. You probably have to remove the bump stop to get to it. If you have 1/2 inch should be enough assuming the shim is about 1/4 - 3/8 inch thick. My pin on my OME 95R’s was long enough to use what was there. YMMV

 

No, the shim is gonna be just about as thick as the pin that fits into the hole in the axle pad. It’s had to be bolted with the new bolt, it’s the new pin that slips into the axle pad. Imo I’d want 3/8-1/2” of threads showing too side of leaf pack.

 

Keep in mind that the shims aren't necessary for all of the trucks after the lift. I have a dclb with heavy dakars and a carrier bearing drop and I had no vibes at all because of the extra length of my truck and less angle over short beds.

 

I wonder if the pin would be long enough on my 96's. Wish I had time to look tonight cause I just need to know lol

 

I guess I'll just have to check. With the holidays coming up I'm trying to be a penny pincher lol
