LC coil lift driveline vibration
Hey,
Since my lift was put on ( 4inch front procomp IFS lift and rear LC Coils) I am getting a driveline vibration between 50-60 mph. Anyone else with this issue? Solutions / tips, etc ?
Thanks!

Alignment was done and steering is tight....its totally somewhere in the driveline. The best way I can describe it is a low pitch "vrum vrum vrum vrum" over and over between 50-60mph.
Jim, whats the best way to measure the pinion angles? I'll crawl under it tomorrow and take a look.

I dont have my factory manual any longer so I was interested in making sure I got the right grease. ( I believed the 3rd generations used 2 different types of grease ).... just wanted to get it right.

THIS IS FROM THE WRITE UP - Does anyone have their 1999 manual handy to see if this is true for the 99 as well ? Apparently in 2000 it was changed.
Thanks in advance !!! BTW- thanks Jamie for finding it !!!

If your 4runner requires two grease types, buy two pistol grip (one-handed) grease guns. It will save you alot of time. As for the grease type for a 98 4Runner, Toyota recommends two different grease types for the driveshafts: for the u-joints, use NLGI #2 Lithium Base Chassis Grease. For the slide yoke and double cardan joint, use NLGI #2 Molybdenum Disulfide Lithium Based Chassis Grease (Note: I have read that from 2000 to 2002, Toyota standardized the grease type to one kind). So if you are not 100% sure, look in your owner's manual and follow it. . Of course, you can substitute any type of compatible synthetic grease as well (I'll switch to some type of Amsoil grease soon), but again, follow the manufacturer's recommendation.

i seriously doubt your vibration is caused by the LC coils. many people have had them in and no vibration.
that 4 inch procomp lift on the front, thats another story. you need to check your pinion angles up front, and dropping the front diff that much (i assume this procomp lift drops the front diff with a new truss, to save your cv angles) could cause the pinion angle to be incorrect if it was installed incorrectly, or the they did not correct the pinion angle.

I would assume that since he does not know much about lubing that it is indeed a lubing problem in the rear!
Nope, I've had no vibration issues back there. I keep it nice and lubed though.
Oh I thought it was lithium, my bad. I just use the stuff that I've had in my lube gun for the last 10 years.
