Not a telescope problem, but I think that the pump hoses are reversed!

Steering wheel and tire issue

Have a front end suspension check done to eliminate any worm ball joints -shockies- worn suspension rubbers-- steering problems. If ok have a wheel alignment done and have the rear end aligned first as it affects the front alignment. The violent wobble is castor wobble and indicates negative castor possible from sagging suspension springs. The camber is out at that results in the car following every dip in the road. The camber has to work in conjunction with the toe-in measurement and if the 2 are not correct then you will have problems.

Have saginaw manual steering gear box on 70 pontiac t/a. steering seems a little loose. how do i adjust saginaw box

There should be two adjustments on your steering box. Loosen the large ring nut at the end of the box and tighten the center adjuster to zero clearance. When re-tightening large ring nut, make sure that adjuster does not turn with it (sometimes it helps to adjust a bit looser so the adjuster ends up where you want it) You will also find another adjustment on the cover opposite the pitman arm shaft. Adjust with wheels off the ground and make sure that after adjustment is made box does not bind. If any binding is noted, back off a bit.

I have a 1999 Ford Ranger 2.5 L 4x2 and after i start the truck there is a slight hum and it gets louder when u speed up the rpms, it also gets really loud when i turn the steering wheel so i replaced the...

Ford Saginaw pumps are notoriously noisy power steering pumps. I have not had any that were not noisy. This is especially true when turning the steering wheel without the vehicle in motion.

It sounds like you may have a bearing race out of spec in your front hub assembly. Check for bearing play by pulling with your hands on each tire--if there is a clunking noise---replace the bearing.

Hi, I'm trying to put a new flaming river steering shaft onto my 1984 CJ& with the power steering. The new shaft has a 3/4'' yoke and 36 spline count, but I cannot for the life of me get it to mount on the...

check the splines for consistency as many have a master spline ( one wider or like 2 as one) so that the steering wheel always ends up in the correct position
you may have to fit a different yoke to the box to take the new shaft
