vibration /motor mts

[RHancock]

I just changed the motor and trans mts in my 92 4x4. they were really shot, now I have a little too much vibration at idle, I am thinking I need to get the injectors cleaned or replaced as it clears up under load and with some RPM. Anyone had the same problem ??? I also was wondering if the aftermarket mts are harder rubber that the stock ones and if that might be causing the problem... ??? I tried raising the idle a little made it better but it is still there...

mine idled better after adjusting the valves. book says it needs to be checked every 12k.

Where did you get aftermarket motor mounts from?

I got the one motor mount and the trans mounts from rockauto.com--- The other motor mount I got from hi-lo here in town... the hi-lo mount was harder rubber than the other which may be some of the problem...



On the trans mounts the price was 6$ each and they showed up in 3 days. Can't beat rockauto as the dealer/******* wanted 15$ each and he had to order them!! (B) In a town of 4 million people and 20+ dodge dealers the wharehouse didn't even have them... go figure...



One thing I forgot to mention was the truck sat for a week while I had it apart putting in a rear main seal and waiting for the mounts. . this may be one of the reasons for the rough idle...



Well I checked the valves and they were fine only one or two that were out a little, I double dosed the fuel with injector cleaner and then ran it down the highway for about 2 hrs real hard. Seems to have helped. I probibly need new injectors I will try the cleaner for 2 or three more tanks and if it doesnt get better I will probiblly have to buy some injectors...



If anyone has some spare POD's they arent using I really need/want them... .

Hey RHancock,

I just changed the trans. mounts last week. I have the same problem also. At idle the truck has a annoying vibration and it goes away with a little rpm. Seems to be going away or I am just getting used to it. Prior to the new mounts it was very smooth. I bought my mounts from the local independent parts house. About $5-6. 00 each. Label on box was "Anchor Industries" #'s 2667,2668.
