1993 Toyota 4Runner-Knocking noise-front end-cold weather
1993 Toyota 4-runner 185,000 miles. I have a knocking noise in my front drivers tire when outside temp. is below 10 degrees. When the outside temperature warms up the noise goes away. It is kind of a knocking, dragging noise when the wheel rotates. I had it in a shop but they couldn't hear the noise because it was warm then. They couldn't find anything wrong. What could be the cause?

This is Caused By the Grease in the Spindle Bearings Getting frozen. Get it Greased up really Well and you Might need to Repack the Bearings on this side to Stop this and Stop further Damage to the Spindle.

Ensure the wheel nuts and Axle nuts are properly torqued to the specification. Lift up the front wheels, place supports under the car and do the following:
- Sit if front of right wheel, slightly move it right and left and feel any abnormal noise if coming out of it. If click-click or Tuck-Tuck sound is observed it could be due to the excessive play in the tie rod end, rack end, ball joint wheel bearing or U joint. Next hold the Tire with your one hand at the top and with other hand at the bottom. Shake the Tire inside out and feel any noise or play. If play is observed, it could be the worn out ball joint or the wheel bearing. Now hit the Tire at the top with rubber hammer and observe any rattling noise coming from near the center of the wheel. If you could listen to the extra noise it could be due to the dried up caliper pins. Grease the pins with graphite grease. If all is found fine, similarly check the left wheel and repair as necessary.
Knocking noise in the air intake or do you mean a lifter noise,because you let it sit the lifter are not charged up or solidified,so you dont get adequate compression when you turn it over.if you have fuel and spark thats fine what about compression,noise from the air intake make me wonder if the timing belt is intacted.
