I have a 1993 Toyota PU 4x4 with a saggy rear end. It has always been this way even when new. I bought some 1.5" blocks to put between the leaf springs and axle but this created a very slight vibration at 65 mph. No one else would notice it but it is there. I removed the blocks and it is much smoother. I would like to raise the rear end just a bit to level out the truck. I thought the blocks would do the trick. I know the diff is at the wrong angle with the blocks.

Any recommendations on how to remedy this. Can I mill the block at an angle to take care of the alignment problem. If so how much would be needed and what issues might I encounter.

I could attempt new springs but that is an expensive alternative. I do not want to raise the truck so the rear is higher than the front. I don't want to do springs as I'm not sure I would get the right ones which aren't too high.

What will be my best option.

 

Do you have a truck spring shop close to you? They can usually re arch springs to sit a little higher. They usually service semi trucks, but they can do pickup leafs as well. Thats the route i would take.

If you are dead set on using the blocks, get an angle finder, measure your pinion angle at factory setting, then do the same with the blocks installed, that will tell you how much you need to shave down. 4Crawler.com sells shims that will adjust your pinion angle, not sure if you could use them on top of the block though.

 

You might find some cheap replacemrnts on amazon

 

you should be able to buy pitched rear blocks and shims at local auto parts stores. if you're getting the vibration now, you'd be getting it with a leaf swap or any other lift in the rear. it's likely a ujoint or the carrier bearing of your 2-piece rear driveline (for xcabs).

another option might be a combination of angled shim/block with a longer shackle. 1" longer shackle = 0.5" lift.

ultimately, you know the best fix is to replace your leafs if you can afford it. i went this route on my 93, with OME leafs and stock shackles - it's a drastic visual difference going from saggy to above stock height, but in the end i am very happy i went this route, but yes the initial rake was surprising. i had the lift with both 31" and 33" tires and it's great with both. to give you an idea of what my truck height ended up as - i'm now at 22.5" from center axle to bottom of fender lip both F/R. truck sits level F/R with BJspacers and some slight tbar adjustments up front.

 

Ever heard of the no cut zuk mod? Search for it on here.

 

if he's getting vibrations now, he'd still be getting them no matter how he lifts the rear end. either change the operating angles of pinion/driveline to smooth things out or address the part causing the problem, if it's even correctable via that route.

 

If you remove the blocks and vibration goes away, then add springs and see if it comes back. If not then you're done.

I just saw you originally said no springs. Sorry I have ADD and didn't comprehend the last 3/4 of your post. If you're worried about getting the wrong size and rate, just read what people are saying.

 

I used 1.5" blocks, not angled and got the slight vibration. The blocks changed the angle of the diff. I just want the truck to sit level and not droop in the rear, blocks seemed to be the quick and cheapest way to fix...maybe not. The truck has always sat low in the rear. I bought it with 7,000 miles, so basically since new. I'd hate to buy replacement spring and have the same issues.

adding a leaf will make the truck ride ruff inthe back I assume.

 

Post up pics so we can see what you're working with. And also search no cut zuk. All you gotta do is slide the springs in.if you don't like it take them out and return them

 

Saggy butt is the way it is supposed to look. That is how they designed them in Japan.

I'd leave it alone and save the money for an PS4.

 

PS4 LOL that would be more of a waste of money for me. At 49 years of age I spend my money on better things...guns, bicycle or motorcycle stuff....way more entertaining!!! I already have the 1.5" blocks I may mill the blocks from 0 to 1/4 and see what that does. Maybe that will get the angle right..if not I can pull the blocks easily.
