First time posting an info thread (I usually need help).
The CV joints in my front end were pretty well crapped out - Grinding at the slightest turn, heavy resistance in the steering wheel - I got a temporary fix for ya.
Your going to need small hole punch(~1mm), WD-40, marine grease, grease gun, pin inflation tip (ex. to pump up a basketball), short(~3") CLEAR hose, and two small clamps. Might be easier if an extra person was with you too.
First, if you have the fitting to go onto to a grease fitting, take it off. heat one end of a 1/4" clear hose, fit it over the grease gun threads. Clamp it good, a lot of pressure will be applied. On the other end of the hose, slide the inflation tip inside the hose, clamp that good too.
Slide under your Jeep, use the hole punch to put a tiny hole in the boot. Spray a bit of WD-40 inside the boot first. Then pop in in the inflation tip, start pumping away on the grease gun(this is where 3 hands would come in "handy"). Pump until you see the boot start expanding. Take the tip out, and voila. Now I know that there is now a hole in the boot, and it is now exposed to everything, but like I said......TEMPORARY FIX. Drive around a bit, just to spread the wealth to all the components inside the boot, do some figure eights, and stress the wheel from side to side.
When all was said and done for me, the steering resistance went away. The grinding was still there a bit, but diminished to a low dull after a while. If need be, reapply as needed. Since Kolak has drained my Jeep budget because of his great prices, I'll have to wait til next year to get the replacement CV joints.
Sorry for the length, and I hope at least one person finds this helpful.
