Worked great!

I put one ton axles under my jeep and needed to ream all the tie rod mounts. This reamer worked perfect for doing that. Just go slow so you don't ream to far.
Pros:
  • Affordable

Great Reamer.

September 10, 2014
I had to modified two steering spindles from 10??_ to 7??_. However the hole for the lower ball joint stud is a little over 1" diameter (on the large end) and this taper reamer barely made it, would be better if I could find a larger diameter reamer. The hole for the tie rod end stud was very easy. When you use the reamer run it at a slow rpm with a lot of pressure for the best results.
Pros:
  • good steel did not get dull.
Cons:
  • needed to be a little larger in diameter
Yes, I recommend this product.

Great tool.

September 04, 2014
I had to ream out quite a bit of material from a forged pitman arm. This did the trick after using several drill to get the rough diameter. With the twisted cutting edges, I could put in a variable 1/2" drill. I used lots of cutting/tapping fluid. It can be used again. I couldn't have cut it by hand. Great. Perfect!
Yes, I recommend this product.

Stays sharp

August 31, 2014
My friend bought this from Speedway and I borrowed it. Will buy my own now that I''ve tried it. Needs a lot of tool pressure to cut which is due to the large amount of surface being machined. Drill press would be best but hard to chuck up a spindle. Needs a strong drill. Yet, with all that pressure on the bit, it stayed sharp and has seen a lot of use. Used gear lube to keep it cool.
Pros:
  • Price
Yes, I recommend this product.

Yes this is the correct taper for a '69 Camaro lower ball joint and also for the Howe 22421 ball joint. You will not need the reamer however. If you get the Howe 22421 ball joints they will press into your lower control arms and fit right into the stock '69 Camaro spindle.

You will need to measure your tie rod end to determine the taper of it. Sorry we do not have any experience with that application to know what the taper would be.

The tapered reamer number 91089411 is 7 degree and correct for enlarging the ball joint holes on your Granada spindles to accept the lower ball joint stud from your 1955 Customline.

Sorry this reamer will not work for your application. The minimum size of this reamer is too large for the tie rods on your Nova.

For the 1978-88 monte carlo they would use a K5208 upper ball joint and a K6145 lower ball joint and will be for the 10 degree ball joint reamer. We offer part number 91089412 or 10680771 for 10 degree reamers.

You will have to determine the taper angle of your tie rod ends to know if this is the correct reamer for your application. Sorry we do not have a listing of the taper angle for a 1970 Dodge pickup.
