Hi, My 95 Suburban does not want to engage/disengage to 4X4 (as quickly) as in its younger years (sometimes 60-70sec.) not that i'm in a big hurry but it is slower than normal. Someone told me it uses some kind of heater to do this and its probably worn out.

Does any one know how this works and how can I fix it ??

Thanks Jack

 

Mine did the same thing it's your 4x4 actuator going out or is out it is
located on the front differential (gear box) it's was $110.00 bucks at NAPA
Easy to Change,,

agreed... my 95 still works ok.... 30-60 sec to engage... which is ok by me for 14 yr old truck...
